Why is my truck not getting 12V power?

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
