Really ... do another search. It's the most heavily debated wire in the car. It's off the PCM, it's off the EICM, and it's off the back of the gauge cluster. Look for my other tach wire posts. And you wont find a green one in the car.

Moderators: We need a "tach wire" as a quick reference. This question is asked a lot, and there's no one clear answer.

Hockyman -- I tapped mine out of the back of the gauge cluster. I removed the gauges, and tapped the lowest of the few white wires I saw. Hit or miss, though. And it helped to slim the wire tap on both sides for more room.
