This installation of TCS T1 Decoder is for HO Scale Model Power FA-2 and was performed by Jean Lacroix, Canada
This model was custom painted and modified to represent a Canadian FPA2. On the first picture, you can see at left the original version of the FA2 and at right, the modified version.
The first action you will have to do is to remove the front coupler of the locomotive by removing both screws on both side of the coupler box. The next step involves the removal of the body. In order to do this, you simply have to pull outwards both side of the body. The body should come off easily.
You will then have to disconnect all the wires that are hooked on the two motor poles through a small angled clip. In the next picture, you can see that part. Keep those clips because they will be needed. Cut the bare metal wire and put it aside, it will be used shortly.
It is on those two parts that you will solder the grey and orange wires from the harness, one for each side of the motor. Then, solder the black wire of the harness to the black wires that come from both the rear and front trucks. The red wire can be attached to the bare metal wire and then slide in the place it was before, on the side of the motor and touching its metal casing and hold by the plastic clip, or soldered to a brass washer that is secured by a screw on the frame of the locomotive.
The blue and the white wires are connected to the front headlight Led as per instructions that come with the T1. The Led was then glued in the clear lens located inside the nose of the locomotive. The yellow was not used for the backup light. Cut back the violet and the green and put liquid tape or electrical tape at their ends. Make sure you use shrink tubing over each connections between wires. The decoder can then simply be installed just in front of the big weight that sits on top of the motor or on top of the front truck and held in place with double sided tape. You are now ready to reinstall the body doing the opposite of what you have done earlier.
