My Dad's looking at buying a trailer and found one with a 2950lb capacity and electric brakes (this won't be for vehicles, but will be used for ATV's, wood, etc). We really don't need the electric brakes but this is a nice trailer for a good price. Here comes the urgent part...we need to buy a trailer this week so we can use it this weekend. My Dad's truck isn't set up (at least I don't think so) for electric brakes. He currently has the standard 4-prong connector. The vehicle is a '97 Chevy Suburban 1500 4x4 with the towing package. What would I need to do/buy to install a 6-prong round connector in place of the 4 prong flat connector in order to make these trailer brakes work? THANKS!
