This installation of TCS LL8 Decoder is for HO Scale LifeLike Proto2000 GP7 and was performed by A.G.
The three upper pictures show the beautiful LifeLike Proto 2000 GP7 with its shell on prior to the TCS LL8 Decoder Installation.
Grasping the shell by the solid area between the grills, lift the shell straight up and off of the chassis.
This picture illustrates the original light board with the DCC-ready plug.

Place our LL8 decoder on the locomotive chassis, reinstall two phillips screws and plug the DCC plug back (as shown in the picture above). For more information on the pin designation please see the manual that came with the LL8 decoder. Make sure Pin#1 of the decoder is lined up with Pin#1 of the DCC Plug.
Hold the shell in one hand and the chassis in your other hand. Lining up the front of both pieces, lower the shell onto the chassis, keeping the lower edge of the shell parallel with the chassis.
