To my understanding


I'm trying to help. Kust go do what I said to do. It will lead you to the issue. Electricity has to get from the brake apply pin in the plug, to the brake actuator, to the frame, and back to the ground pin on the plug. Thinking hard about how this should work will take you much more time than following the steps to figure out why it doesn't. Simple continuity checks are basically all there is to DC troubleshooting.

So I did what you said and I now have two wires on the rv side that I don’t know where they go. I’ve tried connecting both wires to the truck brake pin but the truck still wouldn’t recognize that the rv was connected. I have continuity through both of the wires through each other. I’m not entirely sure what that means but obviously they’re connected together somewhere down the line. Any ideas?

I’ll add that neither wire has continuity when testing it with ground so I don’t think they’re shorted anywhere.
