Important things to note:
Laying cables in between and underneath bricks
Cables can fit in between and underneath LEGO® bricks, plates, and tiles providing they are laid correctly between the LEGO® studs. Do NOT forcefully join LEGO® together around cables; instead ensure they are laying comfortably in between each stud.
CAUTION: Forcing LEGO® to connect over a cable can result in damaging the cable and light.Connecting cable connectors to Expansion Boards
Take extra care when inserting connectors to ports of Expansion Boards. Connectors can be inserted only one way. With the expansion board facing up, look for the soldered “=” symbol on the left side of the port. The connector side with the wires exposed should be facing toward the soldered “=” symbol as you insert into the port. If a plug won’t fit easily into a port connector, do not force it.
Incorrectly inserting the connector can can result in bent pins inside the port or possible overheating of the expansion board when connected.Connecting cable connectors to Strip Lights
Take extra care when inserting connectors to ports on the Strip Lights. Connectors can be inserted only one way. With the Strip Light facing up, ensure the side of the connector with the wires exposed is facing down. If a plug won’t fit easily into a port connector, don’t force it. Doing so will damage the plug and the connector.
Installing Bit Lights under LEGO® bricks and plates.
When installing Bit Lights under LEGO® pieces, ensure they are placed the correct way up (Yellow LED component exposed). You can either place them directly on top of LEGO® studs or in between.
OK, Let’s Begin!
1.) We will start by installing lights to the left section of the castle. Split the two sections and then disconnect the boat house entrance at the very front of the set.
Disconnect the two torch pieces from the front of the boat house then disconnect the two round plates from each side: Take out the following 2x Provided Black Round Plate 1×1 with open stud and 2x White 30cm Bit Lights. 2.) Carefully bend the bit light component from each light up on a 90 degree angle as shown below: Place the Bit Light facing up inside the bottom of one of the provided Black Round Plates. Secure the light in place by reconnecting the two round plates from one of the torch pieces over the top as shown below. Reconnect the torch section back to the brick with clip ensuring the cable is facing the back. Repeat this step to install another Bit Light to the torch on the other side, then reconnect both sections to the outside of the boat house. 3.) Reconnect the boat house back to the front of the set ensuring the cables are laid behind and in between studs of the rear wall. 4.) Follow the below images to disconnect pieces around the entrance courtyard side wall Lay the two Bit Light cables from the boat house across and then up the wall through to the inside of the court yard. Hide the cables behind the tree pieces and stone pieces. Lay the cables in between studs before reconnecting pieces we removed earlier to close up the wall. 5.) Disconnect the following section to allow us to remove the two side window sections near the great hall clock then disconnect the 1×1 plates from the bottom of each section. Take a White 30cm Bit Light and place it over the stud of the 1×1 plate. Secure it in place by reconnecting the section over the top. Repeat this step to install another White 30cm Bit Light to the other side. 6.) Reconnect the left section and then thread the cable through the space of the right window as shown below: Take the right section and thread the cable through the space of the right window before reconnecting this, followed by middle section we removed earlier 7.) Take a 6-Port Expansion Board and connect the bit lights from the front of the boat house as well as from either side of the clock to it. Test the lights we have installed so far by connecting the USB Power Cable to a spare port on the expansion board. Connect the cable to a USB Power Bank and verify all lights are working OK. Disconnect the USB Power Cable and proceed to the next step. 8.) Remove the following pieces along the rear wall of the courtyard. Take a 30cm Connecting Cable and a 50cm Connecting Cable and connect one end of each cable to spare ports on the 6-port expansion board. Take both connecting cables and thread them over to the other side of the castle as shown below. Turn the set over and pull them out from the other side and ensure they are both slipped down the following space in between walls. Lay both cables down in between studs before reconnecting pieces we removed earlier surrounding the rear wall. Ensure the components and cables are all neatly tucked into the sides so they are not obviously seen from above. 9.) We will now light up the lamps running along the left side of the castle. Starting with the first three, disconnect the following section which they sit on then disconnect the black lamp posts as well as trans yellow round plates. Take 2x White 30cm Bit Lights and install them to the first two lamps by placing the bit light directly over the black lamp post and securing it in pace by reconnecting the trans yellow round plate over the top. Bend the cable slightly up at the base of the lamp post. This will help lay the cable down later on and help conceal the wiring. Reconnect the two lamps to the base. Take a White 15cm Bit Light and install it to the third lamp post then reconnect this back to the base. Reconnect this whole section back to the outside of the great hall then lay the three cables down toward the left side as shown below: 10.) Disconnect the next section along where the next three lamp posts are connected to. Take 3x White 15cm Bit Lights and install these to the lamps, following the same method used in previous step. 11.) Disconnect the two sections which the remaining three lamp posts are connected to then install another 3x White 15cm Bit Lights to them as per below except this time, ensure the cables are facing directly behind rather than toward the left 12.) Take a 12-Port Expansion Board and connect all nine light cables to it starting with the first ones we installed to the first ports on the right of the board. Take a 15cm Connecting Cable and connect it to the far left port on the expansion board. Take your USB Power Cable and connect it to the next port along. 13.) Disconnect the three lamps on left side then neaten up cabling by first grouping the first six bit light cables together closest to the expansion board and then folding and twisting them around each other a few times so they bunch up nicely together. Tuck them into the space in between expansion board and edges. Reconnect the three left lamp posts then group the cables closest to the expansion board and then fold and twist them around each other a few times then flatten the cables. Secure the cables underneath the plate section below then tuck the cables inside the following space underneath. Tuck in any remaining excess cables to prevent them from being too obviously seen from the outside. Hide the USB Power Cable and 15cm Connecting Cable underneath the following plate: Test all lights are working OK by connecting the USB Power Cable to the USB Power Bank again. 14.) Take a 6-Port Expansion Board and connect the other end of the 15cm connecting cable to the far right port. 15.) We will now install lights to the four torches inside the great hall. First disconnect the four torch pieces and then disconnect the flame pieces from the pearl gold bases. Take out the following provided 4x Pearl Gold Round Plate 1×1 with open stud Take a White 30cm Bit Light and then slightly bend it up on a 90 degree angle as shown below. Place the Bit Light (facing up) inside the pearl gold base. Secure the Bit Light in place by reconnecting one of the provided Pearl Gold Round Plate with open stud over the top (upside down). The Bit Light’s LED should be showing through the hole of the round plate as shown below: Take one of the flame pieces and using a pair of scissors, cut the tip off the bottom of it then reconnect the flame piece to the torch base. 16.) Repeat the previous step to install another 3x White 30cm Bit Lights to the remaining three torches then reconnect each one back to the great hall ensuring the cable is facing behind and in between clips. 17.) Take a new 6-Port Expansion Board and connect all four bit light cables from the torches to it. Take a 5cm Connecting Cable and connect it a spare port on the expansion board. Connect the other end of the 5cm Connecting Cable to one of the OUT ports on a Flicker Effects Board. Take another 5cm Connecting Cable and connect it to the IN port on the Flicker Effects Board. Take the other end of the 5cm Connecting Cable and connect it to a spare port on the 6-port Expansion board from the right side of the hall. Test the Fire torch lights by connecting up the USB Power Bank again and verifying all is working OK. 18.) Take a Green Strip Light and using it’s adhesive backing, stick it to the base of a provided LEGO Plate 1×6 Take a 5cm Connecting Cable and connect it to one side of the strip light, then connect the other end of the cable to the 6-port Expansion board on the far right side of the set (expansion board without the fire torch cables connected to it). 19.) Take the other end of the 30cm Connecting Cable we pulled over from the front side of the castle and connect it to the other side of the Green Strip Light Using it’s LEGO plate, mount the strip light to the ceiling of the chamber of secrets as shown below: 20.) We now need to hide the wires from the four torches in the great hall. First disconnect the following sections on the right of the hall. Lay the two right cables across and then down the right side in between studs. Lay the two left cables across and then down in between the next studs to the left of the right cables. Secure them down by reconnecting sections over the top. Disconnect the four torch bit light cables from the 6-port expansion board and then twist the cables around each other so they come together forming a larger cable. Reconnect the bit lights back to the expansion board. Neatly tuck all the components into the space on the right side of the chamber of secrets then hide the connecting cable on the right side underneath rock pieces. Turn On the USB Power Bank to verify all is working OK 21.) We will now move onto lighting the inside of the main tower. Disconnect the large wall sections from each side of the tower by pushing them out from the inside at the top and bottom using your finger, then pulling the entire section out. Disconnect the right side of the roof and then pull up the other end of the 50cm Connecting Cable from the bottom of the tower. Secure the cable in place underneath the following dark grey piece on top of the tower. 22.) Take an 8-Port Expansion Board and connect the other end of the 50cm Connecting Cable to it then disconnect the left side of the roof. Take another 50cm Connecting Cable and connect one end to the expansion board. Thread the other end of the 50cm Connecting Cable through the right side of the tower and then pull it all the way out from the left side. Secure the cable underneath the dark grey brick on the side then bring the cable all the way down to the bottom of the tower. 23.) Take a White 30cm Bit Light and a provided Trans Clear Plate w Rounded Bottom 2×2. Place the Bit Light facing down in the centre of the trans clear plate then connect it underneath the roof of the first staircase room (at the bottom of the tower) ensuring the cable is laid toward the right. Bring the other end of the bit light all the way up to the top of the tower and connect it to the 8-port expansion board then tuck the cable underneath bricks in between floors (slightly disconnect and reconnect section over the top of the cable) Take another White 30cm Bit Light and a provided Trans Clear Plate w Rounded Bottom 2×2. Place the Bit Light facing down in the centre of the trans clear plate then connect it underneath the roof of the second staircase room ensuring the cable is laid toward the right. Bring the other end of the bit light all the way up to the top of the tower and connect it to the 8-port expansion board then tuck the cable underneath bricks in between floors (slightly disconnect and reconnect section over the top of the cable) 24.) Take a White 15cm Bit Light and a provided Trans Clear Plate w Rounded Bottom 2×2 and connect them underneath the roof of the top staircase level ensuring the cable is laid toward the right. Connect the other end of the white 15cm bit light to the 8-port expansion board then tuck the cable underneath bricks in between floors (slightly disconnect and reconnect section over the top of the cable) 25.) Take another White 15cm Bit Light and a provided Trans Clear Plate w Rounded Bottom 2×2 and connect them underneath the roof of the very top floor ensuring the cable is laid toward the right. Connect the other end of the bit light cable to the expansion board then turn ON the USB Power Bank to verify all lights in the tower are working OK 26.) We will now install lights to the two torches. First disconnect the round plates from each side and then follow method used in step 2 to install a Bit Light to each torch using provided 2x Black Round Plate 1×1 with open stud. Use a White 15cm Bit Light for the right torch and use a White 30cm Bit Light for the Left torch. Carefully bend the bit light component from each light up on a 90 degree angle as shown below: Place the Bit Light facing up inside the bottom of one of the provided Black Round Plates. Secure the light in place by reconnecting the two round plates from one of the torch pieces over the top as shown below. Reconnect the torch section back to the brick with clip ensuring the cable is facing the back. 27.) Reconnect both torches to the tower then take the right torch cable (White 15cm Bit Light) and connect it to the 8-port expansion board Use the LEGO Removal tool to slightly disconnect the the top section of the tower to create a small gap. Slip both of the cables underneath (in between studs). Pull the left torch cable out the right side before securely reconnecting the top section of the tower then connect the left bit light cable to the expansion board. 28.) Eliminate excess cable by pulling up all six cables and grouping them together close the expansion board . Twist and fold them together so they bunch up nicely as shown below. Neatly tuck the components inside the space on the right side of the roof then reconnect the main right wall section ensuring there are no visible cables hanging out on the sides. Reconnect the right roof section then use some tape to tape down the cables along the right side of the tower. 29.) Before we reconnect the main left wall section we are going to install some lights for the tower windows. First disconnect the following sections of the tower. 30.) Take one of the thinner upper and lower wall sections and disconnect the following trans black plates only. Take a White 30cm Bit Light and with the cable facing to the right, place it directly over one of the studs where the trans black plate was disconnected from. Secure the bit light in place by reconnecting one of the trans black plates over the top. Repeat this step to install another 4x White 30cm Bit Lights to these two sections ensuring the cables are all facing toward the right side. 31.) Reconnect both of these sections back to the tower starting from the left side, then reconnect the larger centre wall section ensuring the five cables are pulled out. Connect the five Bit Light cables as well as the other end of the 50cm Connecting Cable from the bottom of the tower to a new 12-port Expansion Board then turn the USB Power Bank ON to verify all the lights installed in the tower so far are working OK. 32.) Take the remaining upper and lower wall section of the tower and install 5x White 30cm Bit Lights underneath the following trans black plates (same as we did for the other wall section of the tower) Reconnect these two sections back to the tower then connect the five Bit Light cables to the 12-port Expansion Board. Turn ON the power bank to confirm all the lights in the tower are working OK. 33.) Take a 30cm Connecting Cable and connect one end to the remaining port on the 12-port Expansion Board then pull all the cables down the edge of the tower and secure in place with your index finger. While still holding down the cables with a finger, group the cables together and twist and fold them around each other to eliminate excess cable then push the cables into the space at the bottom of the tower in between walls. Push the expansion board inside this space to completely hide the component and wiring. Ensure you keep the other end of the 30cm Connecting Cable out as we will require this to connect up to the other side later on. 34.) Reconnect the left roof section then ensure all cables are tucked in neatly in between walls before reconnecting the main left wall section. This completes installation of lights to the left side of the Hogwarts Castle. Turn ON the power bank to ensure all lights we have installed so far are working OK. 35.) We will now install lights to the right side of the castle. Take this section and disconnect two lamps (round black and trans yellow plates) on the left side of this side, behind this side, and from the outside of the viaduct hall entrance (6 in total). 36.) Take 6x White 30cm Bit Lights and follow the same method used in step 2 to install them to each lamp section using provided 6x Black Round Plate 1×1 with open stud Carefully bend the bit light component from each light up on a 90 degree angle as shown below: Place the Bit Light facing up inside the bottom of one of the provided Black Round Plates. Secure the light in place by reconnecting the two round plates from one of the torch pieces over the top as shown below. Reconnect the torch section back to the brick with clip ensuring the cable is facing the back. 37.) Reconnect two lit torches to the left side as well to the outside of the Viaduct hall entrance. Turn the set over and remove the two pillars before reconnecting the two torches to this wall. Using a LEGO Removal tool, create a gap underneath the torches in the following position then tuck each cable underneath to lead to the other side of the wall. Reconnect the two pillars then reconnect and close up the gaps ensuring the cables are neatly laid in between studs. 38.) Disconnect the following brick and then group the two cables from each side together and lay them down along the floor in between studs before reconnecting the brick we just removed over the top. Continue to lay the two sets of cables underneath rock pieces to secure them down the edges of the castle. 39.) Remove the following pieces from the left side of the Viaduct Hall entrance. Lay the cable from the left lamp down in between the following studs before reconnecting the 1×2 brick over the top. Disconnect more pieces from the outside of the entrance then lay the cable from the right lamp down and across the ground in between studs before reconnecting pieces over the top. Bring both cables down the edges of the set and hide them underneath the following rock pieces. Be careful doing this to ensure you do not pinch the cables (which will result in Bit Lights not light up) 40.) Take a 12-Port Expansion Board and connect all six Bit Light cables to it. Bring the left side of the castle over and connect the other end of 30cm Connecting Cable from this side to the 12-port expansion board on the right side of the castle.
