reverse

I have a 2002 And the reverse lights won’t turn on when I out it in reverse. I’ve checked the 2 fuses in the fuse box under the hood and changed bulbs and they still won’t turn on any help please. Really need them working.

Hey, I was wondering where where is the reverse wire by the driver side, instead of running a wire from the tail light to the dash? I’m trying to wire my reverse wire from my new head so whenever I put the truck in reverse my backup camera automatically switches to the reverse screen.
