I finally got my brake controller installed. I backed up the coach to my trailer close enough to get the plug in. Running lights work good, trailer brake controller senses and fires the trailer brakes, turn signal and hazards work but my brake lights will not come on. I don't even get a 12v signal on my left or right at the plug. I'm using a 7 pin setup and plugging into my 1 yr old enclosed trailer. I'm thinking maybe there should be a tail light converter or maybe there is a blown fuse somewhere. Leaving for Moab Thursday. HELP!

Eric-

What year and model of coach?

How many pins on the coach hitch connector? Did you install the connector, or did it come to you as is?

A 2002 Windsor owner's manual (link here), page 2-33, shows what is now considered "non-standard" wiring, where the turn signals and brake signals are not combined. This was common for the time. What does it show in your coach's owner's manual?

"Standard" wiring diagrams here.

A 12V tester can solve this pretty fast. Test the turn/stop pins to see if you get 12V when someone mashes the coach brake pedal.

I think I figured it out. I need a 3 to 2 wire converter. The brake signal for lights is on a separate wire. The trailer I have has signals and brakes on the same circuit.

Sheesh what a day.

THX for jumping in to help.

Cheers!

Eric-

Make sure you wire the converter upstream of the motorhome's hitch connector. That will convert your coach to "standard," as every "normal" trailer or toad expects.

I wasn't getting a hot wire at my plug on ou r05 Monaco to power the wireless brake controller. Did some digging around & found there was no hot wire at the flat plug on the coach side, the plug side has a red wire, the other side has a hole where the connector would be. I had to rig a hot wire to power my brake controller.

This is what you need to install. I tried a cheaper one, and it lasted less than a year.

I was able to install a 3 to 2 wire trailer light converter in the rear run box and then run the wires the short distance down to the trailer hitch light receptacle.

I used this 3-2 converter from Curt.
