reverse lights

2004 4.7 limited 350k _no reverse lights--which fuse or any ideas?

 

Check to see if anyone spliced in a 4-pin harness out back. If so, look at the point they spliced it, check for wiring damage/rot. It’s a super common source of rear lights failing to work.

But of course, “new to you truck”, now is the time to check EVERY fuse in the dash. And if you haven’t read THIS THREAD yet, it’s time to get off your ass! Pay attention to the water leak section. Just in case it’s not trailer wiring bullshit like others found, and it’s it’s not a burnt or missing bulb, and it’s not a fuse, there may be other stuff afoot.
