If it's on a Ford chassis there is a socket under the dash for the controller and all the wiring is run to the back of the original chassis frame supplied by Ford.
The plug under the dash needs a jumper harness to the brake controller. It's chassis specific i.e Ford, Workhorse, etc. The jumper harness has a plug on one end that matches the socket under the dash and a plug on the other end that matches the socket in the controller. Sometimes the socket under the dash is hard to find. It's usually taped to the steering column, but can be found almost anywhere in that area.
As I mentioned earlier all the wires for the trailer hitch socket (including the #10 blue wire for the electric brakes) are run to the end of the original chassis by Ford in a harness along the outside of the drivers side frame rail.
Winnebago extends the wires from that point along the frame extension to the trailer hitch socket on the rear. In our case we found they ran all the wires except the brake wire to the socket. For some reason they opted not to run that wire. We found it labeled, folded back, and taped off in the harness just like Ford delivered it to the factory.
If yours is like ours it doesn't take much effort to extend the wire to the socket. Ours needed about 8' of #10 blue wire and a butt connector. I just opened the harness, removed the tape from the original wire, butt connected the new and existing wires together and ran the new wire in the existing harness to the socket.
Once at the socket I had to remove it from the bracket, disassemble the 2 halves, and run the new wire to the only open connector. Reassemble the halves, reinstall it to the bracket and give it a test. The whloe process took about 1/2 an hour.
