Installing Brake Controller

What is involved in installing a brake controller on a '04 4x4 Z71 GMC pickup. From what I gather I plug in under the dash and mount controller above legs on driver side. What do I need at the rear of truck to attach to the airstream? Do I run wires and plug to the back? And what do I need on the airstream side? Have a '70 Overlander.

Piece of cake. I got an '04 Burb and it's pretty much a plug and play, except for connecting the truck wiring harness connect to the brake controller. Pull out the dummy fuse and install the fuse and yer off.

I think it takes at most 20-25 minutes, if that. Everything is prewired. As for what a 70's Airstream has or needs, I'll leave that to the vintage folks to talk about, but the truck part is a slam dunk.

The brake controller has 4 input wires. There is a pigtail (or harness) with the matching 4 wires that inserts into a plug located somewhere under your dash (talk to your dealer's service dept.). Sometimes the pigtail actually is in the glove box of a new truck. You may need to rig up your own pinch connectors. Isn't there a 7-pin plug on the back of your truck near the hitch area? See here and here.

From what info I have gathered, this is how it should work. I will be getting a Tekonsha model, it comes with the harness to "plug-n-play" under steering and mount unit under the dash. It plugs in and then uses the 7 pin light system already installed at rear bumper to which the airstream will plug into. The airstream brakes use the voltage from the 7 pin light hookup when the brake peddle is applied in the tow vehicle. No other wiring is needed, Correct????
