My son just got a 2006 z71. It has the six pin wire hookup for a trailer. ( I guess all Z71's have the tow package?) I'm going to take the brake controller from my truck, and put it in his. How is this done? Are there simple wires under the dash for hookup like I hope? I had to wire my 89 Silverado from scratch. I'm not looking forward to that again.

If it has the "7" pin at the rear then it should have the plug under the drivers side of the dash.

Just buy the harness, probably like $20.00 then plug it in and then wire it to your brake controller.

The controller wiring harness should plug in behind a panel under the parking brake cable. Remove the wing nut, remove the panel and plug it in.

Ok, not to hijack this thread, but I have a related question, which is why I'm not starting my own topic. My '09 Silverado LT didn't have a hitch or any trailer "package". I just put a hitch on and replaced the dummy block in the bumper for the 7-pin wiring plug. I got a Tekonsha P3 trailer brake controller and the instructions leave a bit to be desired. I found, what I believe to be, the wires under the dash for the controller, but the colors of my wires don't match their instructions. There's a label on the vehicle's wires that says what each wire is (5 in total) but there's only 4 wires for the controller.

I've searched practically everywhere for help on this, but I'm left scratching my head. Can a brother get some help?

archangel46 you might find this helpful! http://www.etrailer.com/faq-tb-0007-2007-2009-GM-Full-Size-Truck-Brake-Control.aspx

Thanks, Silveryrado! That's what I needed! I don't know how I missed that. I used the search on etrilers' site with several combinations of search words and all I got was generic Chevy/GMC instructions.

I'm a noob here too, and this is one of the questions I've been searching... I'll be watching this post for anybody with information on where to plug the pig-tail that came in the jockey box with my 2004 Z71 Silverado...

Cricket, cricket...

Found it above. The truck that I purchased 2004 Z71 5.3L Silverado had a harness in the jockey box, and I followed the directions and plugged it in. After splicing it into my Prodigy P3 and installing the bracket, it took about 20 minutes total time. Plug-n-play. Don't forget to plug a 40amp fuse into the "Stud #1" spot in your fuse box. This will send 12v power back to the positive pin in your factory installed socket at the rear. This will a) charge battery on the trailer or b) provide lighting to the trailer (like a snowmachine trailer) if you have it set up to take your truck power for the interrior lights.

I hope this helps. I can't want to do some more work on this rig, and I"m relieved that when I purchased the truck, it's never had a break controller installed in the truck. It makes me believe that it's never really towed a large trailer. It came out os SoCal (LA area) so I know it's had most of it's miles on the freeway.

archangel46,

Splice the GM wires to the Prodigy P3 in the following order:

1) Black on the break controller splices to the Red on the Truck wiring (Ignition 12v if you want to test)
2) Red on the break controller splices to the Light Blue (smaller wire) on the Truck Wiring (stop light switch if you want to test)
3) White on the break controller splices to the Black on the truck wiring (yes, they are both ground if you want to test ohms)
4) Fat Blue wire on the break controller splices to the Dark Blue truck wiring (this is the trailer power)
5) The thin brown wire on the truck gets doubled over and taped, it's not used for this particular controller. It's powered with the headlight switch...
6) Lastly, don't forget to install a 40amp fuse into "Stud 1" in the fuse box. As you're facing the fender/motor, it's the upper left most fuse hole. It most likely has a red blank installed into it from the factory, unless somebody has removed it. It's for 12v constant power to the trailer when towing, to charge the battery and such.

I just did this tonight with no problems...

Let me know if it works out well.

I just realized that my spelling sucks... it's "Brake" controller, not "Break". I guess I needed a break when I wrote this.
