Re: Factory trailer brake controller and plug?

I loved those.

At that time I was driving company owned vehicles, so I could browse the fleet, pick whatever I wanted, and within a few minutes have my brake controller installed and ready to rock and roll.

Another enthusiast and I independently discovered a problem in that way. When the Global A electrical architecture was released for the 2003 model year they changed a couple pinouts and didn't tell anybody. The net result was no trailer brakes. I realized it while I was on the phone with the Electrical system engineer trying to figure out why I had no brakes; the other guy found out when he hit the end of his driveway.

They ended up releasing a new jumper harness, with a new part number and a color coded connector as a result. I still have a library of those harnesses in the cabinet.
