This Cab Forward has the Tomar Adlake Marker Lights installed and working. It also has a white LED for a headlight that is controlled by the DCC decoder in the tender. I used 4 pin Deans Micro Plugs between the boiler and chassis for the lighting power connectors in all my Cab Forwards for compatibility.
The DCC installation in this Cab Forward is finished except for touch-up painting and gluing the Monkey Deck back.
This is a closeup of 4294 showing the wiring from the DCC connector to the Faulhaber 2224SR motor and the Deans 4 pin connector for the marker lights and headlight. I used Goop glue to hold the motor in place.
