So I know this may be a long shot, but I was wondering if there was anyone out there that uses the "Prodigy P2" brake controller in their tow vehicle. Actually, anyone with good knowledge of brake controllers may be able to help with this problem!
Basically, the brake controller isn't working. When I hooked up the light connector from my boat trailer to my truck, the brake controller flashes n.c. This means "not connected". I do know that the brake controller works!
We had an issue with the trailer lights not working when I first bought the boat and trailer. As you can see from the pictures below, I wrote up a little diagram to show how the lights are wired. At 5 o'clock, there is a blue wire that is suppose to control the trailer brake. At 7 oclock is the white GROUND wire, 9oclock is a yellow wire that controls the left signal, etc. I believe that thing in the middle has something to do with by-passing the brake controller when backing up.... but I'm not 100% sure.
Does anyone have any thoughts?
