The instructions aren't clear and I'm sure Bj is asleep right now and won't be able to answer till tomorrow. But I dug into the wiring tonight and was hoping someone on here would be able to answer the question real quick so I could get the car back together. I bought the single VMP booster and I know I that I need to wire it to both FPDMs, but do I also wire the power wire to both power wires or only to the drivers side wire.
