Do you have a chassis wiring diagram for your coach? The 7 pin connector may or may not be shown in that diagram, but it’s a start for where to look for how it’s wired.
It’s possible it was installed by the coach builder in which case the coach wiring diagrams might show it.

Problem is, trailer tow harnesses can be factory installed or installed by an individual shop - and there is no specific protocol for installation if not done by the factory.

Was in a similar situation with my Fleetwood. I finally used a 12v light tester and probed all the fuses there. Found two that were blown. They were marked as Ignition. Yeah...I guess. When troubleshooting, remember that the 12v power to the plug is only enable with the key on. Best of luck.

I looked at my chassis and house wiring diagrams, I could not find anything specific to the trailer plug.



One thing that I found on my rig was it came with a 6 pin connector, not common. Works for me but I have to watch it as there is not a good locking system to hold the female portion in place.

But I found that there was another connector buried in all the wiring looms right in front of the engine.

I do not remember any fuses in the rear that protect the wiring harness. If there aren't any the fuses in my front drivers front run bay would be the one's I'd look at if I had a problem.

Knight 7 pin relay

The problem has been fixed, theres a relay for the tow plug in the curb side battery bay next to battery kill switch which was unmarked, all is good, Tim
