Hey guys, so a while back I put some OEM leather seat covers with heaters on my seats and I was wondering if anyone knew how to wire them? I install car stereos so I have limited knowledge of wiring, the top and bottom heater wire into eachother and I'm left with a harness with 3 pins (I'm guessing pos high, pos low, and neg) Anyone know how to do this install with the factory seat heater switches?

Thanks in advance
