Fuel pump wire in PCM, Ground or 12v? I am wiring up my LQ4 in my Typhoon and had a question about the fuel pump wiring.
Does the fuel pump out on the PCM supply 12v to the fuel pump relay, or does it go low (to ground) in order to trip the fuel pump relay?
I got a hotwire harness from Racetronix, and wanted to make sure before I go and try to hook it all up.
Thanks,
