09-13 CTS-V Headlight Pinout for Switchback Halo's
Looking for a wire diagram for the headlight connectors.
Edit:
Finally had time to do a little testing. Here's what I got so far. On the side of the ground it seemed like some other wire possibly could be DRL's? Also there's a thin black wire at the end of the uncharted side, could be an additional ground source? Like a return ground?
