when i wired in my aem fic i tapped the crank sensor wire going into the ECU....im at work right now, but if you don't get an answer, i'll let you know later

...IIRC it was green too


::edit::

wait, that might have been the color of the wire on the fic....

If it's a 1MZ, then you're going to want to use the black wire as a tach signal.

Black wire on the ignitor correct?

thanks

Black/red should be right. If it doesn't work, let me know.

hmm still no luck i'm wondering if i need a MSD tach adapter so the window switch gets an accurate signal.

Are you going two stage?

[trd4life]

nope single wet 90 shot for now until i get the Eaton M90 Supercharger that i am fabricating on the car.

Just to verify with what I have, what are the colors of the wires?

The red/black goes to the starter.

try at the harness going into the ECU. The 4th connector (D) pin 16..should be black and red
