Just wanted to share my Stewart C628 RP install.
The Base DC Locomotive comes with 8 pin plug, and the circuit/light board has directional lights/built in resistors - Yellow/green and Red LEDs (directional), but oddly - no white head lights?
I may try to wire them in in future.
Anyway - Simple install.
8 pin to 9 pin adaptor harness - 3" digitrax part DHWHP
LM3s Module
11 mm x 13 mm cube speaker - crude engineering with baffle.
I usually use the Digitrax short 1" 8 to 9 pin harnesses, byt needed a bit more length to get module to front of the board.
Also had to extend the brown speaker wires a tad to reach the speaker in rear.
Taped the module up to bottom of board, and DF taped speaker with 3M foam tape - simple and easy.
Works Great ! Enjoy -- hope this helps.

That's one nice & simple install there. Thanks for sharing!
That's a good trick with that Digitrax wiring harness. I was unaware that was an option. I can see how it can make life simple. I will certainly keep that in my back-pocket for a future install.
