Can anyone help me locate the trailer brake controller harness on an 06 E450? I have asked at the ford dealer, various auto parts stores, an rv dealer, searched the net, and can't find an unused connector. I did find what I thought was it just behind and above the emergency brake. It is a six pin rectangular connector, gray, with four wires in but it has something with one wire connected to it that splits into three wires using a butt connector. It is obviously after market, and I'm not sure where it goes. When I shop for the wire harness that connects to the brake controller, the ones I have seen are completely different shape, size, and color. I can't find a picture of one online, either.

That sounds like the correct connector. The RV builder may have spliced off of it to use for other uses.

You need this plug:

Recently installed that part number in an Explorer with factory tow package. What I want to share is...

...The Power Lead (black in the adapter harness, probably different color in the Ford wiring harness) was HOT in the Explorer even with the key off. So disconnect the battery or pull the electric brake fuse. Else, good chance of blowing that fuse. I called an RV shop and they said they use circuit breakers when they do a from-scratch install, but just leave the 30A fuse if it's a factory package. Since I'd blown the factory fuse, I got an inline ATO fuse holder, put female spade connectors on it and plugged where the JCase fuse came out. Then put a 25A auto reset ATO breaker in the holder. That way an accidental short won't leave the brakes inop till the fuse is changed.

Also, the amp rating should relate to the number of axles you're braking.

Why would plugging in a brake controller blow the fuse? The pigtails can be wired before its plugged in.

Well, er... On the Explorer, the harness connector's behind the glove box. Why a connector opposite where the device'll mount, who knows. I taped the four wires together to form a "point" and poked it through the maze behind the center of the console/dash. Plugged it into the harness, put the glove box back. Took the tape off the "point" and crimped the ends to the controller's ends. When I went to test the controller, no power. Only explanation's that I blew the fuse when I plugged the glove box end in.
I just got the process out of step and don't want somebody else to. I tested for power and brake signal with the key ON, never thought to try it first key OFF.
