Recently bought a 2000 GMC 3500 with 5.7 vortex engine. Nice truck, but
does not have brake control valve.
Sometime back I was browsing this newsgroup and someone asked about
installing a brake control. The reply was be sure and get the specific
control for your truck so you won't have to splice any wires.
Does anyone know of a control I can buy for this truck that will not require
cutting and splicing wires to install?
1. Get the harness, something like this.
2. Get the controller, something like this.
3. Get a Stud #2 fuse. Sorry I don't have the amperage rating.
4. Remove the cover that you always rest your left foot on while driving.
5. Connect one end of the harness here.
6. Mount the controller.
7. Connect the other end of the harness to the controller.
8. Replace the fuse blank for stud #2, with the fuse from #3.
You do have a 7-way connector by the bumper, right?

If you have the factory hitch then you should be already hard wired to your

a female opening that says "trailer brakes"Your controller should plug in to
this slot.When ordering your controller make shure and get a harness
specifically for your truck.That would have to be hard wired to your
controller unless you get a controller that has a male-male plug...then it
plugs in to fuse panel and other end plugs in to controller....Sid

should be 2 wires just dead ended under your master cylinder. The other end
of these are behind the rear bumper. You can use them for the brake wire and
for constant 12v if you just hook them up.
I second the Prodigy controller. Excellent unit. Comes with good
