Two different threads that will help you.

3 wire hookup. + , - , and Pin #10 right out of the lower (red) connector on the PCM for 1999-2002. For 1998s it's a white wire coming out of Pin #35 on the BLUE connector. It's a white wire that will be tapped and go to the tach signal on your tach/shift light.



Only one wire goes into the engine bay, the tach lead. There is a grommet on the passenger side firewall behind the PCM. You'll have to remove the PCM to get to it. Drop the kick panel on the passenger side floorboard and you're golden.


Both the power and ground will be inside your car. I tapped the pink wire from my TCS switch near my shifter. You can also tap into the fuse box on the drivers side of your dash. There are three smaller slots on the fuse panel, marked ACC, IGN, BATT. The Ignition will be fine, since you only want power going to the shift light when the ignition is on. And as stated, it will need to be set in 4 cylinder mode. It has something to do with the pulses being sent.

Nope, it's gotta be on 4. If it's on 8 it will be WAY off. Sounds weird, but it needs to be this way due to the firing order on LSx's.
