Where to Ground Trailer Light Harness on a 2004 Chevy Colorado
Updated 12/08/2014 | Published 12/07/2014 >
Question:
Need to know where ground location is for tail light wires without trailer connection put on. It back feeds through directionals on dash when applying brakes.

Expert Reply:
If I am understanding you correctly your vehicle brake lights are activating the turn signal indicators on the dash of your 2004 Chevy Colorado when the brakes are applied.
This could be due to the # C55510 not being grounded properly. You will want to run the white, ground wire directly to the frame of your vehicle. See the picture and install video I attached.
