One wire alternator question
One wire alternator question I put a 2001 Trans Am LS1 in to my RX7. I had my harness modified by Speartech. Is my alternator going to charge? I heard that I have to take a wire and install a light bulb in line with it for the alternator to sense the resistance and charge the battery.
Anyone help me out?

Re: One wire alternator question Yeah, the PCM controls that wire on 99-up systems. No need to add a bulb or resistor. Just hook up the large gauge wire to the output stud and away you go!
