This installation of TCS DP5 Decoder is for HO Scale Kato EMD SD40-2 Mid 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

Pictures of Kato EMD SD40-2 Mid with its shell on prior to the TCS DP5 decoder Installation.


Grasping the shell at the center top of both sides (being careful not to crush the grills), lift the shell straight up and off of the chassis.

Remove the DCC plug.


Place some Kapton tape over the metal screw and yellow capacitor.


Plug the TCS DP5 into the 8-PIN socket as shown in the picture above. Pin#1 is circled in red. Our 5 function decoder will provide you with working ditch-lights. All you have to do is press F0 to activate the headlight and than F1 to activate ditch-lights.

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.
