1- LM3S - Sound Module
1- Sound Systems Speaker and Baffle
-little Capton tape, 3m 2 face for speaker,

Stock lights had resistors built in.
No cutting required, Plugged, taped, soldiered speaker wires - DONE
Easiest one yet. Maybe 20 minutes.

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...
