This installation of TCS LL8 Decoder is for HO Scale LifeLike Proto2000 GP7 and was performed by A.G.

Important Soldering Tip:
Please do not use any flux either liquid or paste on the mother board. It will damage it. Use only Rosin core solder approved for electronics use.
We recommend to use only Kester "44" rosin core, SN63PB37, .015" diameter, part number 24-6337-0007.
This can be ordered from Techni-Tool under Techni-Tool part number 488SO157



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.

Unscrew the two screws to remove the original light board.


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.


Other solder tips: When stripping wire, only strip a tiny little bit of the insulation. Strip no more then a 1/64 of an inch. When the wire gets tinned with solder the insulation will shrink back more. Try to not expose any more wire then half the length of the solder pad at most. In no case should solder or exposed wire wire ever be outside the boundary of the the solder pad you are attaching a wire to.
