I was trying to hook up a tach directly to the ecu. Cause my stock cluster one doesnt work. But using the pinout everyone is giving me (same one u said) it doesnt work.

in the r33 (rb25) FSM there is a pinout on page 265. you can download the fsm over on racebread. the adobe page for the pinout is 286 (265 in the actual fsm). its slow at work and so ill try to help out a little bit. here are pictures of the FSM

I figured out which one was my tach signal and on your pinout above its number 57. Which on your listing is saying thats the exhaust temperature sensor signal. So this cant be the right one for my ecu.. As far as i know i have a regular r33 ecu. Is the ecu any different if its automatic?
