This can be ordered from Techni-Tool under Techni-Tool part number 488SO157 http://www.techni-tool.com
This installation requires a two function decoder. The
Train Control Systems T1 decoder is the best choice. It fits "plug n
play" with the connector supplied with the locomotive. The locomotive
light bulbs are 1.5 volt but the necessary voltage dropping resistors and diodes
are mounted on the locomotive light board.
1. Remove two Phillips head screws on underside of the loco.
There is one screw located on either side of the fuel tank between the
tank and the trucks.
2. Remove couplers
body straight off.
4. Remove jumper board that is plugged into the 9
5. Plug T1 decoder into the harness. We formed
the harness wires slightly to allow the T1 decoder to seat against the light
board as shown in the picture.
6. Test operation. If all is ok,
reinstall body with the screws. Reinstall the couplers and the
installation is complete.

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.
