Need to get a trailer hitch and I have seen prices vary as much as $200 in price. What do I need to get? Wiring is no big deal on the coupler. I know they have their "proprietary" plug-in. I'l just splice and put a regular 4 way on it. Universal trailer wiring is: Black = ground - Yellow = Left turn - Green = Right turn - Brown = clearance or running. Way to remember it Yellow has a (L) for left and Green has a (R) for right. Anyway, that is the standard 4 wire trailer set-up. No telling what this is!
