No tail lights

I blew the tail light fuse under the dash replaced fuse and tail lights worked for a while then blew again I found the wire that was exposed at the rear of truck but now I have no power to the tail light fuse under the dash just wondering how do I get power back the fuse

 

A lot more info is needed

are these OE or aftermarket? anything else that’s wired to this?

have you checked the harness all the way to see if anything is cut or chewed?

 

They are stock no aftermarket and nothing else wired found wire that was exposed at the rear of truck causing the fuse to blow but now I have no power to 7.5 amp fuse under dash everything else works brake and turn signals work fine just no tail lights or tag lights because I have no power to fuse

 

What wire at back of truck?

 

OP Must be using talk to type.

 

The tail light fuse is powered by the tail relay.
The tail relay is powered by the 120A JB/Alt fuse.
The tail relay is commanded ON by the Body ECU

 

Small green wire that goes to the tail lights that had rubbed on frame and became exposed causing the 7.5 amp fuse to blow fixed wire just don’t have any power to the 7.5 amp fuse trying to figure out why it doesn’t have power

 

Thanks I’ll check that fuse to see if that’s the reason I have no power to the 7.5 amp fuse under dash

 

If that fuse was bad, you’d have a lot more problems than tail lights.
If your power windows work, the J/B 120A fuse is good

 

Yea my power windows work so I can rule that out then

 

Is the headlight switch On?
It has to be set to Tail/Park or Headlight.

Try both positions.
