Sweet... seems like easy peasy.Just get the OEM or direct replacement 7 pin jack. The harness is right behind the bumper with a cap on it. Plugs right in. To get the constant hot and the trailer brake controller connected you have to connect to the two bare studs at the front edge of the under hood fuse panel.
Why the constant hot isn’t already connected is strange to me. It’s coiled up and taped to the side of something a few inches below the master cylinder.
Will be planning on doing it all when we get the Tahoe wrapped. figured will be pulling the rear bumper anyway so while it is getting wrapped, will replace the rear reinforcement bar and put in the trailer 7 pin. do we have a part number for the plug?
