nothing in the manual mentions the trailer brake or stop lights. The closest I see is Trailer Tow park lamps but those are working. I have lights when I turn on the lights just not brake or turn signal.
Without going into the fuse panel and where or how to find the fuse, if you plug your trailer connection tester into your truck socket, does it test good? Yes, then it's in the trailer wiring. If it tests bad, then find the fuse panel that has the turn signal fuse(s) and using you DMM check the fuse. No power check the flasher, power through the fuse, check the wiring from the fuse to the truck socket.
On my '97 F150 there are actually three fuse blocks to be checked, under the dash, two, side by side on the left inner side of the fender under the hood.
