Bought a Tekonsha Voyager off of eBay. It came with a factory Ford harness (incidentially it came wired wrong)
But under the dash I already have a plug- looks identical (right plug right socket) and has 2 wires already connected and 4 loose wires. It's straight back from the parking brake and the loosey's were bound with electrical tape and 3/4 were capped.
So two fat and two skinny wires. I'm pretty sure this is the place to hook in the brake controller, so I need to know what goes to:
Black: +12 Volts
Red: Stoplight (brakes applied)
Trailer Brake (output to trailer?)
Glad to see you found the real connector - mostly I had forgotten to look for more documentation. My excuse is that I had to change the oil/filter on the diesel.

Thanks for this Jage. I was thinking about installing my controller this past weekend, but was oh so confused with the plug and the capped wires (seemed like it would be the controller connector, but it was powering SMB-installed aux lights, etc.). My mass of wires looks just like your mass of wires. This thread clears that issue up nicely. Send me your bill.
