harlan 2 step question

What wire on the clutch switch are you tapping into, there are 4 and i cant seem to figure out which one the grey wire needs to go to. Car is a 99 so i believe i should be able to tap into one of them correct.

Thanks

You can splice in at the PCM.

Run a search here or on LS1.com for the pin assignments. Pin #40 seems to ring a bell, but I could be wrong.

99+ PCM, pin 32, blue connector, gray wire. This is only true for the f-cars though. Corvette uses a different type of switch and pin to the PCM.

Make sure your factory clutch switches are there and working.
