I am planning on a mod project involving tapping the ceiling dome lights in the front and back. I just need to know which wires in the front dome light harness are for the domes. (Keep in mind that I already know about the already-established way of tapping fuse#6 and the green/red pillar wire- but my lights are going to be in the ceiling, so I need to tap in the ceiling without running wires down the pillar).

There is a harness on the right dome light with about 8 wires:


There are only two wires on the left dome light:


Does anyone know what two are for the domes, and furthermore, which is ground and which is positive?

I know there are wires for the other electrical components (mic, homelink, etc), but I just need to know which are for the domes.
