Yup, running LED bulbs so I'll take the stock single Reverse wire and convert the ford plug into a single hot by combining both + wires to the same female "Mopar Style" plug. The ford ground I'll bond to the body/chassis.
Both circuits combined will still be less wattage than an incandescent 1157 brake only wattage.
I usually tie all of the tail/turn/brake mounting studs in the trunk together for a good ground connection. I'll do the same with these.
