Jay,

I double-checked my original adaptive headlights. There are no additional connectors - only the harness. I'm 100% positive. The adaptive must be wired in the harness and/or controlled by a module like the LCM near the glove compartment.

I remember seeing another thread with some headlights that were NOT adaptive (can't remember the year) but had a separate connector - for the self leveling.

I'm gonna search and see if I can find a pic of a non-adaptive bi-xenons anyways.
