I have an 04 MCS that I installed 06 door panels with a REAL arm rest. What a difference. If anyone has info regarding the wiring harness and where to connect it, I'm interested in making the lights under the doors functional.

Dealer isn't much help. Saying I shouldn't install something that didn't come stock on the car.

 

You'll have to feed the wires through the rubber tube that the speaker wires go though, then into the car under the dash and solder the wires to the foot light. You'll have to clip off what ever connector came with the door panel lights to get it to fit through that tube.

It will be rather involved. Search the audio subforum for wiring new speakers w/ crossover under the dash.
