This installation of TCS MC2P-SH Digital Decoder is for HO Scale Atlas Silver GP40-2 Phase I and was performed by A.G.

The three pictures above show the beautiful Atlas Silver GP40-2 Phase I with its shell on.
Remove the fan compartment as show in the picture above (just snap it off). Marked in red is a close-up of the original lighting board where the DCC plug can be seen.
Picture of the same board with the DCC plug removed. In the upper left corner of the DCC socket, you can see a small triangular mark (circled in red) - that is the "pin #1" indication (orange wire).
Plug the MC2P-SH into the DCC socket so that the orange wire is lined up with the "first pin indicator."
Place the whole decoder installation close to the original light board so that the fan compartment can be reattached.

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.
