Searched high and low and did not see any info on hooking up a break controller. Saw lots of posts where people say just look for the blue wire. Thought I would go ahead and post up my results for others in the future.
Found the wiring harness directly behind the steering column.
Called Tekonsha before I stater this endeavor to ask about a plug in wiring harnes adaptor, they had no clue, so just skipped it, and spliced into the wires.
The wires are as follows:
Big Fat Pink= Power
Small Little Pink= Brake Light Wire
Black= Ground
Blue= Trailer Brake Line
Whole thing start to finish took about 15-20 minutes. Really wanted to mount the brake controller on the left side of steering wheel so as not to be seen when walking into the coach, but there is just not a lot of room over there to do a real clean look. Ended up putting the controller under the ignition switch and tucked back as far as possible so its flush with dash.
