Question about 2007 GMC Envoy Denali
I need a wiring diagram or fuse box diagram for 2007 GMC Envoy Denali trailer towing package problem. It's a 7 wire auxillary plug. The trailer brakes work fine, but all the lights do not come on. I don't know if it is a fuse or in the wiring. If it is a fuse, I need to know which one.
Here is the wiring diagram for the trailer wiring for your truck.
Hope this helps

The problem might be related to a faulty ground on the trailer. If the lightson you envoy work, then the problem is either a bad ground or a wiring problem with the trailer hookup.
