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.

Important Soldering Tip

Please do not use any flux either liquid or paste on the mother board. Over time, the acidic properties of liquid or paste flux will begin eating away at the fiberglass PCB and will damage it. Use only Rosin-core solder or no-clean flux approved for electronics use.

TCS recommends the use of Kester "44" Sn63 Pb37, .015" diameter Rosin-core solder. Kester part number 24-6337-0007.

You can order this solder from the following retailers:
Digikey - PN:KE1110-ND
Techni-Tool - PN:488SO6775

Other solder tips

When stripping wire, only strip a tiny little bit of the insulation. Strip no more than a 1/32 of an inch. When the wire gets tinned with solder, the insulation will shrink back more. Try to not expose any more wire than 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.
