2016 Thor Chateau - Chevy - Brake Controller

[Cerviperus]

New owner of a 2016 Thor Chateau 26B on the Chevy 4500 chassis. The RV was used by the previous owner to pull a toad with a Blue Ox setup, but I'm not sure if the receiver hitch & wiring is factory or not. It does have the expected 7-pin round connector. My plan is to pull a flat trailer behind the coach with either my wife's car or our SxS depending on the trip.

I've seen many posts various places referring to the factory brake controller wiring harness location on the Ford chassis, but I can't seem to find anything on the Chevy. Does anyone have any suggestions on where to look for it, if it indeed has one?

Thanks.

Edited to clarify I'm looking for the brake controller harness.

Are you asking about the brake controller harness?

Yes. I already have a Prodigy brake controller - I use it when towing with my Tacoma - so I'd love to be able to just grab a new Tekonsha pigtail and be set.

Found it. If anyone stumbles across this later, the 4 wires (no connector) were wrapped in white tape and tucked up under the dash just beneath the steering wheel. They were even labelled & tagged with matching descriptions to the following page in the owner's manual. I had assumed the hitch & 7-pin connector was a factory option since it was in the Thor brochure, but didn't want to assume that was a guarantee.

It probably was factory. The brake controller pigtail is normally left unconnected for the owner to install their own brake controller. The fuses for the brake controller and the charge line are also normally not installed until the owner installs them.

@16ACE27 - Finally got around to wiring in the pigtail for my Tekonsha brake controller this weekend, and moving on to testing determined that you were absolutely correct, the wire to the trailer brakes was NOT wired into the 7-pin socket at the rear. I was able to follow it from the under-dash pigtail, through the firewall, and into a main wire harness, but I lose it from there. Any idea if these are typically spooled up and tucked away somewhere, or if it's easier to just run a new one from the pigtail to the rear?

Thanks for any tips.

Well I would start at the 7 pin connector - they may have just wired in the 4 light wires and ground and left the power and brake wires in the bundle there. If it isn't that easy, the "run a new wire" play may be the best solution.
