2008 f250, no trailer lights but brakes work
I hooked up a buddy's trailer that had been in a field during a brush fire. It sustained minimal damage but some of the wiring got melted. Well now my trailer light plug has no power for any lights. The brakes work fine but no lights, not running, braking, or signals and there is no power at the plug for lights. I assumed fuse, but checked the ones that I thought they could be and they were fine.
I would assume the trailer lights shorted out and blew a fuse but I checked all of them with a test light and didn't find any blown. Any relays?

Possibly, but wouldnt that affect the trailer brakes also? With a test light at the plug, there is 0 power except on the brake pin when brakes are applied.
Any idea what fuses for sure control the trailer lights? I checked all of the fuses in the.kickpanel and all the ones I thought could be right under the.hood

did you actually check in the wiring harness BEFORE the bed plug connection?

understood.. no power at the plugs.. fuses seem good.. check the relays.. I think there is one you can swap.. maybe the brake relay for the light relay.
then check the connection for the bed plug..
