The rear connector has an orange, white and blk/gn wire going to it. The wiring diagrams show the connector, but not how it's connected to the power distribution panel under the hood.

Here is a pic of the two connectors. The grey one is from the rear of the truck the black one is from the power distribution panel under the hood.



The OEM connector for the brake controller under the dash has the blue wire, but I can't follow it up under the dash and I'm assuming since it came with the truck it goes into the power distribution panel under the hood.

I did find a picture showing two connections going to the power distribution panel, so I'm going to look for those now.
