    Haha, I do not have a heated garage at my CT house, but I do in VT. Only problem is we rarely bring Tahoe to VT. Since the snow last weekend it has be very dry and very cold, 11.7 this morning.

    In my picture, in the NAT socket, the red wire is the cold side of the brake circuit, the white wire is the parking light circuit. Sooo, on my truck, the red wire goes to the brake controller brake wire, and the white wire feeds my aux fog lights.

    Now, for your trailer harness: look at the bracket attached to the firewall, under the brake booster, this is where my wires are located. What I can't remember is if this where I found them originally.

    There should be a blue and orange wire taped - either to that bracket, or in the frame rail where it curves up under the footwell/firewall on the drivers side. It's been awhile since I did mine, so I'm sorry for the memory loss, but I'm leaning towards the frame rail location. There should be enough wire to finish the run to the fuse block and cabin, so it's a pretty big loop.
    Anyway, the orange wire needs to be terminated and put to one of the 30a posts in the underhood fuse block - that's your trailer power. The blue goes through the firewall grommet and to your brake controller.

    Hope this helps. Also, I used an aux. contact in the seven blade plug to run a backup light to the back of my camper. It's cold here, too, so you'll have to wait for that one

    Good luck,

    forgot this @Conlan Rose
    You were right the wires were directly under the brake booster connected to a bracket using a wire clip. I just today attached the aux power to the fuse box and ran the blue to the cab. I will post pics once I upload them.

    Does any one have a pin out for the brake switch on our trucks? I need to splice in the the cold side of the brake switch but I don't know which wire it is.

    Mine doesn't have pins in that location and I don't know why... So I need to tap in to the cold side of the stop switch.

    Huh? Well, you could run a test light around the harness. I'll look around and see what I can find.

    I found this, but I can't verify it.

    {A few years ago I found these instructions when I was wiring up a Prodigy brake controller for my 1996 Tahoe. The instructions for the '96 Tahoe worked, but I can not vouch for the 1997 instructions. At the time I copied them to a MS Word file and I don't remember where on the internet I found them. Hope it helps.
    ------------------------
    Specific Wiring Instructions for GM Tow Vehicles

    1995-1996 All GM Tow Vehicles: The brake control's RED (stoplight) wire splices into a specific WHITE wire on a 10-pin connector. This connector is located to the left of the steering column. It is coming from the main loom of wires going into the instrument panel. The connector is WHITE and is wrapped with gray foam tape; it will have two WHITE wires exiting the connector. The correct wire is the WHITE wire located in corner (F position) of the connector. Splicing into this specific wire will eliminate any problems with electrical circuits associated with ABS or the cruise control. }

    Good luck, I'll keep looking...

    Thanks for that info at least thats a start I'll keep looking as well incase I also find something because this info is very important to others who own this generation of truck.

    I need to tap in to this for 2 reasons, one for the obvious the brake controler and second to use as the trigger for my light bar project's center light because I need a brake only feed.

    The switch should only have 2 terminals, one is always hot and the other is switched. A 12v meter should tell which is which.

    It has 6... not sure why. I think it is to detect how far down the petal is. Notice the rod in the picture below. Very odd in my opinion. Right now I'm in Wilkes Barre, PA for a campus visit at PSU Wilkes Barre so I can't look at the truck until tomorrow.
