Brake Lights Don't Work Southwind 35K

[jyjcbs]

The brake lights don't work on our 2019 Southwind 35K. Turn signal lights work, hazards work, running lights work. It's just the brake lights. I can't find
where the brake lights fuse is located. Help.

Online manual for 2019 Ford F-53 chassis is here. Passenger Compartment Fuse Panel (page 85 of the manual), fuse 8 is listed as "brake lamps feed." Start there.

Note that Fleetwood was not obligated to use the Ford-provided circuits from the turn signals switch to the lights.

As mentioned. Start at the 7 pin trailer plug then at the 6 or 4 pin plug near the baseplate.

If good there, your next stop will be behind the taillights where the diodes are typically placed.
The jeep wiring doesn't operate the rear lights when your towing it. Only the short section of wiring from the diodes to the bulb sockets back there.

Still working on the brake lights not working but everything else is. Fuse good. Has anyone found a hidden fuse box besides the one by the inside drivers side and the fuse box in the engine compartment. All Fleetwood told me was they
tap off of the Ford fuse box for the tail and brake lights. Lot of help there. He said it's a Ford problem. If they tap off of the ford fuse box, then how is it a ford problem. Also, I'm not getting any power to the 7 pin trailer receptacle which seems odd.
In the manual, they show a "UPS distribution #3" box which has a fuse specifically saying Stop Lights. That is what I'm not sure about. Does this even apply for our RV. Don't know what they mean by "UPS" It's a 2019 35K, chassis is a 2018.

Any chance it is the brake switch on the pedal?

My first instinct would be to check the switch behind the brake pedal itself. This is what activates the circuit
