Okay so i got my kit in from slam specialities on friday and bam im gonna install it this weekend!!! I got the rear 6 link all bolted on ready to go and start the front after realizing that you need to connect the air line before you bolt the cup up i started wondering about the valves positioning. I can see how they go in line but what about wiring them up b/c all i got with the instructions said that one connector on the DIN is ground (optional) and the other two say positive or negative!!! im so confused and i have to get my truck out of my dads shop by monday so they can work on the lift! SOMEBODY PLEASE HELP ME OUT!!!!
