Try pin 17 or pin 23.

careful tapping into IGF or IGT. If the tach impedance is too low, it will pull the signal low, and teh car won't run.

The correct place to tap into it is the ignitor itself. The ignitor normally sends the signal to the tach. The standard wire is black with red dots on it IIRC.

isnt there quite a few black and red wires on the igniter? does it matter which one i tap into?

I tapped into the Blue one with a red strip and my tach works perfect all of the other black wires there didnt give me anything.

Are you guys talking about hooking it up to the stock tach gauge or after market gauge?

I've tried using an 89+ 7M-GTE tach with my 1JZ (cut black wire w/ red dots) and ran directly to pin 6 of connector A on my dash. Am I supposed to just tap into the black and red wire coming off of the ignitor w/o severing its original connection?
