Truck out of shop; so far ok except license tag light not working. Where is the connector located,cab was removed for repairs. Rain has prevented from looking.

 

the lite runs off of the running lites/tail lite harness if you have running ,maybe bulb or wire that pig tails over to lic plate? I dont think theres a fuse, Just for tail,stop fuse,but you may want to look at fuse cover to be sure.
