The lack of space meant using a plug connection would be rather difficult, so I 'hard-wired' the four connections between the chassis and shell. These are the two track pickups to the decoder, and two motor wires from it. The lights and speaker are in the shell and wired direct to the decoder. After final testing heatshrink is slipped over the soldered wire joins to protect against shorts - almost certain otherwise with that metal motor casing. |
