2004 Revolution, tow car is a Ford Escape hybrid.
Never had any problems with the wiring for the tow vehicle till today.
All lights are working correctly on the motor home. I have a 6 pin connector. I'm not getting power to the plug on the motor home for the left turn signal, and the left brake light isn't working The right turn signal is working and the right brake light is working on the tow vehicle when hooked up. Help!!

Check the 7 pin connector on the motor home side to see if one of the pins is pushed in.

Bad fuse. Finally found the fuse box, that wasn't the biggest chore. Even Fleetwood couldn't tell me exactly where it was. Just that it should be in on of the rear compartments. Turns out it was the Battery compartment.

Don't think its not your tow or harness. My last 05 had circuit breakers for trailer plug. They are self reseting. Car shorts it and you unplug to test and it resets. Good luck

We had a similar problem with our 2006 Phaeton on a Freightliner XC Chassis in early 2007. We have a module in the rear passenger side compartment that drives the toad light system, we lost the turn signal and brake light on the passenger side. I tapped into the motorhome's passenger side turn signal at the tail light and added a wire to the back side of the 6 connector plug. This solved the problem until we had the complete module for towing changed out.

There's another option -- Tekonsha Modulite. The system works by induction so no need to run new wire or cut into existing.

If I read your post correctly, the toad is a non issue. I assume you've used a test light on your motorhome plug and found the left turn wire is dead. This should be the YELLOW wire. First thing would be to ensure this wire is good. I.E. not disconnected inside the receptacle. Trace the wire backwards as far as you can looking for a frayed or broken connection. Worst case is you'll have to run a new wire.....Dennis

then i'd check for continuity in the umbillical and also in the wiring from the toad connection to the bulb socket. also could be a loose ground at the bulb socket.

No Diodes, I wired the lights for towing separately. The problem is in the motor home. All the lights work properly on the motor home, but I'm not getting a left turn signal or left brake like at the plug. Right turn, right brake, tail lights, all work on the toad when plugged into the motor home for towing. I've check the back of the plug, and it's fine, I'm not getting power to the plug for left turn signal and left brake.

On our 2005 Fleetwood Excursion there is a small fuse panel in the top back of the first compartment behind the right drive wheels. The fuses in there control the turn signals and other things on the toad.
