Hi I have a 2005 silverado with the towing package. I bought a brake controller to install but the brake controller has 4 wires and the supplied jumper harness has 5. Where do you hook up the brown wire that according to the book if for illuminate?

Thanks,

 

I figured it out. The screen on the brake controller goes through Stud #2 in the fuse box under the hood. It's a pink 30 A fuse. It doesn't say this anywhere in the manual.
