Trailer Wiring and Groud Issues

[Rebel_Horseman]

Went to hook up to my buddy's Exxis 3-horse this weekend. Plugged the trailer into my bed plug and go to check the lights. Finally get the running lights to come on but when I hit the brakes the running lights go off and nothing else happens. The brake controller won't light up when the brake pedal is depress but when it's not depressed I get a constant green glow. Oh, my controller is a Tekonsha. Anyway, we check the wiring in the plug and all looks normal, and we crawl underneath and in the engine and check things out. All fuses are OK and we swapped the relays around and everything still works. I crawled back under it this evening and noticed a red wire in the nest under the back bumper that is not hooked up to anything. It's a large red wire that, when I removed the bed plug, goes to the center position of the plug. This is my ground wire I'm guessing. There's another red wire running to the plug on my bumper as well, so I'm guessing this is the same wire and it was never spliced. I need opinions. If I can't make anything out I'm thinking about bringing it to the trailer dealership up here and having them look at it.
