If you follow the 7 pin cable back to the trailer, it will eventually terminate in a box near the trailer box on the tongue.
All grounds are supposed to terminate at that point and one ground wire from that box will run to the frame of the trailer.
I opened up that box last night looking for any stray wires or anything that didn't look right. There are no wires going out from that box to the frame. I wonder if that could be something I should add?
If you want to confirm you have a ground connection through the 7-pin connector, plug the trailer into the truck but without the hitch dropped onto the ball. If the lights work, you must have a ground wire.
