Get you a cheap test light. You can get them almost anywhere. Then you can test each pin. And for trouble shooting Im with Frank, check your fuses. Make sure the wire isnt lose on the back of the plug. Do you have a flat only? Or a round to flat? The connection could be lose in your round to flat plug. So use your test light to check the truck first, and if its working, then plug the round to flat in and check it at the flat…. If its dead on the truck, check fuses.13 PIV w/ 200 MercIG: WarriorRiverCustomRods
