I own a 2005 superduty king ranch diesel. It was outfitted with the aux switches from the factory. Does anyone know the location of the wires from these swithes and possibly the colors? Also, I have an aftermarket trailer brake controller with the ford pigtail connector, does anyone know the location of the other connector under the dashboard? I'm getting the truck ready for a road trip with a trailer, would very much like to use the trailer brakes. Any info you guys have will be greatly appreciated.

 

Ford has a plug that will plug in to their connector under the -- and wire break box. Also they have several wire's that go through the firewall and come out on the driver side for your convenience to add.

 

The AUX wires are behind the fuse panel on the drivers side. Dropping to panel is the easiest way to get to them. They're four blunt cut wires in a bundle.

Ford upfitter switches: Ign- Hot-ACC
Aux-1 [30-amp] Circuit No. CAC05 Wire Color: Yellow
Aux-2 [30-amp] Circuit No. CAC06 Wire Color: Green / Brown
Aux-3 [10-amp] Circuit No. CAC07 Wire Color: Violet Green
Aux-4 [15-amp] Circuit No. CAC08 Wire Color: Brown

 

Isn't there aplug for the electric break

 

My came harness that plogged in and and all I had to do was wire it to my break box.

 

The upfitter switches (4 auxiliary) have four wires that come out above the fuse box. There are four other wires that start behind the fusebox and come out under the hood (pass through wires) and are not connected to the upfitter switches but can be connected to the blunt cut wires from the upfitter switches that are located behind the fuse box if you desire. The following link shows the installation process for the upfitter switches (not working right now, but if it does come back on, you can scroll down to the end it gives you the info you need on the wire locations). Hope this helps. Just so you know, you pretty much have to drop the fuse panel to see the upfitter switch blunt cut wires. If I remember correctly, they are all orange with a different coloured stripe on them.

I found the details
Aux-1 Circuit No 1936 wire color: Orange/Lt. Green [30amp]
Aux-2 Circuit No 1933 wire color: Orange [30amp]
Aux-3 Circuit No 1934 wire color: Orange/Yellow [10amp]
Aux-4 Circuit No 1935 wire color: Orange/Lt. Blue [10amp]

If you use the search function for upfitter switches you should find more information on here as to the colours of the wires.

texastech beat me to it.... took too long to find the info I was looking for.

 

Thanks for the info guys. I'll take a look and let you guys know how I made out.
