(controller) the black is positive and the white is negative. The blue on my 03 is hooked to one of the blues under the hood . I just noticed that i have two blue wires dead headed up to the fuse box under the hood. I hooked my blue controller wire to one of my blue wires under the hood and i have trailer brakes. I can take a pic if that helps you. Its prolly all different on a 06.
The moral to the story. I think your blue wire has to be hooked to the blue wire in your harness and you will have brakes. when pedal is applied.

I'm thinking differently.

The large blue is the feed from the controller to the trailer brakes.

The red is likely the feed from the vehicle brakes TO the controller. So, I am guessing (on your old plug) the Med red should follow out to a light blue wire that is part of the truck's wiring harness.

BTW, where are plugging this pigtail into?

Is the pigtail plugging up directly to the controller or you having to wire it to the controller? Are you have to wire it to the truck or are you plugging it in the box behind the brake pedal?

PARAGON,

I am plugging into the interior box behind brake pedal, The plug has bare ends that I am connecting to bare ends on the controller using wire crimp connectors.

Do you have a voltmeter?

I'm guessing you need to figure out which pin is the brake feed from the truck and wire it to the red wire on the controller.

Plug in the new pigtail and figure it out by trial and error. Sorry can't be much more help.

Best I can do is to tell you what color wire goes to each pin. I ended up taking the Hummer harness a part and used a voltmeter. My H2 is outside work, so let me know if you want me to get the pin-outs for you and I will get back to you.
