Door handle lighting wiring
 

Now that most of the maintenance on my car is out of the way for the time being, I can start with the upgrades. Some cars it seems came with door handle illumination standard as part of "BMW Ambiance Lighting." Mine, of course, did not. I have "Ambiance Lighting" in the both overhead dome light modules, but not the door handles, sadly.

I took off my front passenger door panel to investigate and see if maybe the wires were in place and just not connected. Here's what I found:

Every harness seems to be connected to something except for one, which has 4 wires leading out of a 4-pin connector.

1. Red/White
2. Blue/White
3. Brown
4. Red/Green

I've checked the WDS and can't seem to find the right diagram. Can someone tell me if this is the right wire set for the illuminated door handles? Thanks.

Sorry to resurrect a 3 year old post, but does anybody have pics of their (lighted) int. door handles so I can compare?

dude i dont think so. The connection is very small and delicate, i think its only a 2 wire connection, live and earth which from memory i think will be red/blue and brown.

There's a relay too, somewhere... Ah, screw it. I've got to go up to the dealer again anyway for a flickering oil pressure light (which they just fixed 4 months ago) and a TPMS retrofit, may as well sweet talk my way into the back and have them show me what's involved. I'll post the results in case anyone else wants to do this.
