I'm just in the process of fitting my MY98 WRX with a NOS anti-lag system that will be contolled by a throttle position sensor switch (electronic snoop type), an RPM switch (the same as the other) and then shut off by a pressure switch.

What I need to know are the following:

1) What wire is for the RPM signal. I would imagine its one from the crank sensor?

2) What voltage does the TPS output. Max to min would be good as the switch is adjustable. Also which wire?

Cheers for any help.

Wayne.

 

Anyone?
