No power to trailer light connector on my 2017 Dodge Ram Lonestar

[Pancho1310]

Bought a 2017 Dodge Ram Lonestar. Love the Truck but the pigtail on my boat was to short. Made the connection anyway and no trailer running stopping or blinkers. The chase begins and find I have a bad led so replaced it. No change. Found out I had a bad ground connection. No change. From the beginning I ran a hot wire from the battery to test all of the wiring. Check the fuses. Fuses all good unless there is another hidden fuse box somewhere. Finally tested all of the wires coming from the truck connector and bingo, no power to the running lights. So checked the fuses again and all good. Am I talking about a bad use box connection or what here. I'm a little baffled on what to do next. Any suggestions?

When you checked the wires from the truck, did you have your headlights on?

Is the connection good at truck?
I mean where if plugs into plug behind bumper?
I had my rear bumper replaced and they didnt plug it in tight when they replaced bumper...
Just a thought

Good morning Poncho, I had the same issue. What I found was a chaffed thru wire where the wire bundle runs around the left front cab mount.
