Chevy 3500 Truck. I have a 4 prong flat at the back of the truck. I need to pull a trailer with electric brakes. The only wires I have at the back of the truck is the Brown, yellow, white small and black. I do not have any of the large wires at the back of the truck. I need to know what I need where to hook in the large wires on the truck so I can use a tekonsha controller and the reverse lights. Thanks
