I rewired my boat trailer per instructions, but no lights. Troubleshooting included rechecked ground (white) wire, used a volt meter to check the car 4-way connector, each light wire and even the bulb socket. All had power. Still no lights when I put the bulb in the socket. Any ideas? Thanks

Hello, I have a 1999 GMC digger Derrick utility truck and it has a round 6 pin plug on the truck side. The trailer I'm going to pull is a large 37' pole trailer and the trailer has a 7 pin round plug. I can't find an adapter anywhere and I think I have to build my own, need some help!

Awesome page. I’m trying to replace my 6-pin plug with a 7-pin on my gooseneck trailer. Brakes have worked great with an adapter in the past. When I look at the wiring in the 6-pin, the brake pin is not connected and there isn’t a blue wire. Just a black wire on the 12V center pin. I noticed the page said “Note: In some applications, the black battery power connection and the blue brake controller output connection are reversed.” I’m totally confused how the brakes have been working with the factory brake controller without the brake pin being used. Any help would be appreciated.

I have a 2001 GMC Sierra 3500HD with no factory installed trailer connection. How do I connect the red controller wire to the brake switch or other brake light cold wire? Thanks,
