Trailer hitch wiring problems...
I have a 2008 G6 and am trying to connect the trailer hitch wiring harness to my tail lights. I have 4 wires: White (ground), Yellow (left turn), Green (right turn) and Brown (tail light). On my tail light wiring I have a Red and a Purple going into the brake/tail light bulb. Which is which?
Example: Yellow wire (left turn) goes to Red or Purple?
I realize that had I bought the pig tails with plug in's for your lights this would have been easier. But I'm trying to go with what I got. Thanks in advance.
