Hello Anthony,

 

O.K. I am sure it is probably raining where you are, it is here, so I need you to get under the rear of the truck. You will see a brown wire coming from your tag lamps. The wire splices into the tail lamp circuit brown wire. Take a test lamp and probe the wire. Got voltage? If so, and your lamps are the ones that the housing screws or pushes into the hole, you may have a rust issue that is causing a loss of ground, or bad sockets. {happens}

 

If there is no voltage, follow the wire ti the splice. You may find that once upon a time this truck was wired for trailers, and the wire is damaged.

 

Finally, any probing you do, like pricking a wire to test, take some silicone and dab the hole you made and wrap it in electrical tape, or we will be doing this again some day.

 

Good luck Anthony, and if you need me, I am here.

 

Scott.
