If only every model had that much free space to install modules in!

If I recall correctly, DigiTrax harnesses are the crimped wire type. This means instead of cutting / coiling unused wires you can lift the little tab the holds the socket into the JST plug and simply pull the wire and socket out; saving them for reinsertion later if need be...
