Door handle lighting wiring

[e30mpower]

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.
