sr20det tach hook up

[napz510]

I have an after market tachometer (autometer), where can i get the signal from the sr to make this autometer works? The number 2 pin shows tach signal but it doesn't work. Anyone knows?
Thanks in advance..

The orange wire. It's in the FSM.

I think the Orange wire is for the start signal not for the tach..

First, you need to tell us what kinda of SR you have.

You can read this thread: http://zilvia.net/f/engine-tech/293028-ultimate-s13-sr-wiring-guide.html

I only cover the redtop so I don't guarantee any other variations of SR.

Pin 3 Yellow/Red at the ECU plug is the tach signal from the ECU. You can tap it here or there are several other places you can tap it if you follow this wire and see where it goes.

Because this is an aftermarket part, we can't conclusively tell you how to hook it up.

You need to call Autometer tech support and work through them to hook up their part.

Correct. It's the start signal from the ignition switch.
