Trailer Controller Information 2000-03 - Chevrolet Suburban, Tahoe - GMC Yukon, Yukon XL Some customers may comment that when the headlamps or park lamps are on, the brakes on the trailer are always applied, or that the back lighting for the trailer brake controller illuminates only when the brakes are applied. This condition may be due to wiring changes within the vehicle electrical system for the 2003 model year. Inspect the brake controller wiring harness jumper that is plugged into the vehicle relay block body. The relay block body is located under the left side of the instrument panel near the left kick panel, behind a plastic cover. The 1999 through early 2003 wiring harness jumper that plugs into the relay block will have a reddish/brown 6-way connector and a tag with the last four digits of the wiring harness part number.
