[QUOTE="Bob Landry, post: 247155, member: 7025"] Agree. If anything works, your grounds are good as they all connect to the trailer frame. BTW, that's not the most reliable way to connect grounds. I ran white wires for ground from my plug to every light, but that's another story. Check for 12V at the truck plug. You should have 12V between the pins that go to the brown and white wires. If you have it there, but neither side, then you have a problem between the plug (brown)and where the two sides connect somewhere in the tongue. You have it on green and yellow because those work, but it may not be on the brown. At this point, you are time and money ahead by picking up a new wiring harness and pulling through the frame. It sounds like you have a bad connection and the others may not be far behind and you could spend a lot of time running them down. You can get a complete harmess about anywhere for around $12. That's how I would go. I would rather spend my time fishing than fixing electrical stuff. [/QUOTE]
