Why is my 7 way trailer not connected?
It can sense when a trailer is connected based on the voltage draw so it won’t sent a signal for 12V when using some testers, especially LED testers because there isn’t enough of a power draw. The system requires a power draw on the 7-way and then holding the brake pedal for about 3 seconds until your dash registers “trailer connected”.

Where is the 12V fuse on a F-150?
That 12V power will be on the 1 o’clock pin location on the 7-way so the corresponding wire will need to be probed to test. I’m pretty sure the F-150 just has a blown fuse under the hood. Check your owner’s manual for the appropriate fuse locations tied to the trailer turn/brake lights and replace them to see if that resolves the issue. 70274
