Question about Dodge Grand Caravan
I have a factory installed trailer hitch and 7 pin wiring harness installed on my 2013 Dodge Grand Caravan. I have power to the plug but when I hook up my trailer none of the lights work. When I attach the trailer to another vehicle everything works fine. Have you ever heard of this problem.

Trailers ground themselves through the ball of the trailer, so no additional wiring needed there. Its runs through the white wire on the trailer side of the harness. It gets bolted to the trailer frame with a self tapping screw.

It's a small minivan why are you using a 7 plug wire. My guess it's wired up wrong. Be sure to check your not trying to haul a trailer that's to heavy for your van to tow safely. 4 wires would be all your van should have. 7 plug harness are for trucks with electric brakes and made to tow over 5k pounds. Your van may only be rated to tow 1500 pounds.

If you are going from a 4 pin on your trailer to the 7 pin on the truck. You need to go to parts store or a department store (ex Wal Mart) and look in trailer section and find the adapter. Thats what I did. Also Remember if your lights don't work on trailer, check the plug to make sure its tight or check the fuse under your drivers side rear seat for that fuse box.
