Sorry all, posted this in the Intro section.

I am new to the forum but a lifelong Ford fan and owner. I purchased a used 2013 F150 Platinum SuperCrew with the 6.2L engine. I have hauled my pop up camper twice with "no trailer" displayed. All lights work just fine but the trailer electric drum brakes won't engage, adjust, or do anything at all even when I manually pinch the brake controls.

Fuses, plugs, wires look good.

Any ideas?

Thanks in advance!

Gonna start easy....as some have bought plain higher trims and added brake controllers....may not have be programmed/activated..

Fuses....underhood box...17-30 amp fuse
Interior fuse 37 -10 amp.....dash programming....elec brakes on....not set for electric over hydraulics.....all in the owners manual...+/- button turned up to 10...
​​​​​​​Then adjusted once you know the brakes work and adjusted properly

I found it...started playing with the plug then took it apart and the blue wire was disconnected inside that controls the brakes. Should have started there but I checked the fuses first and the wiring and everything looked good.

Remember Ford Plugs are screwed up from the factory for towing anything but a camper trailer, we have to switch the red and blue wires so the brakes unlock on our Goose neck and Bobcat trailers.
