2008 GTX brake control wiring puzzel .

We are in need of some help figuring out wiring for onboard towing package.
Are there wires there with supplied connector to hook up a brake controller?
We have Georgetown 3600 toy hauler with work horse chassis.
Any reliable help would be appreciated.
And BTW - Stickey - your wall repair is fabulous. did the same repair ourselves due to your helpful detailed posts. It's been 2 years and several thousand miles and it's still holding! Thanks!!!

There should be a harness on the left hand side of column with a brown connector on it. Sometimes real hard to find. You may have to move the wires around a bit to find it but it is there!

Maybe this will help

WORKHORSE Class A Chassis Instructions

Workhorse A-Body Brake Control Connector
Factory Harness
Circuit Identification

UTB Wire Color
Circuit Function

Electric Brake Output Circuit
Brake Switch Signal
The wires listed above are located under the dash left of the steering column next to the chassis fuses & breakers.
A large black label will be attached to the end of the wire drop identifying it as the Trailer Brake Controller Provision.
Use the table above to attach the Electronic Brake Controller to this wire drop.
Cut the 6-pin connector off the EC-4129 pigtail. Connect the three wires that were attached to the connector to the factory wire drop as outlined in the table above. NOTE: Circuit identification is printed every four inches on the factory wires.
Find a switched 12-volt source for the remaining (red) wire that was not inserted into the pigtail connector. Splice the red wire from the pigtail into the switched 12-volt source.
Plug the other end of the pigtail into the connector from the Unified Tow Brake controller.
