Which wire is ignition wire on the ECU??

[Chrisw]

I've got an S15 SR20. Does anyone know which wire out of the ECU is the starter signal wire (cold start wire)??

I know it's the orange wire on the S13's... Can anyone confirm 100% that it is the same for S15??

Ad just to confirm.. when installing a start button on an S13 I know you have to hook up the starter signal wire on my S15 as well? The wire doesn't seem to be there on this car...

I'm not going to lie... I found that... My car does not have a wire there so I figured I was looking at the wrong thing... Oh no. Now I've got a bigger problem. Thanks for confirming it tho...
