Thanks for that info. Have you hooked up TIS at all to determine if the footwell lighting is enabled? That could be why there is no voltage being seen at the multimeter. Looking at the diagram the color code is correct with the Beige and Black wire which routes back to Pin 37 in the Instrument Panel Wire & Instrument Panel J/B on connector 4A and Pin 25 on connect 4A. Apparently those connectors are located in that upward direction in the back of the main ECU. I may fabricate the pin outs with wire and test my theory for people who are missing that part of the harness.
