First of all unless you got turbo or N20, you wont blow the engine even if you redline it hard,it'll just fuel cut...I know, I did it many times....however if you want the tach, tach signal comes from a purple and white wire coming off the obd-ii port next to the firewall driverside under the hood

oh so matter how hard i rev it i wont blow it? it will just cut out how sure are you of that well never mind ill take your word for it so u sure my car has one....o2 pro dx?

macdaddyslomo

er, uh...mine is a 1.6...but the 2.0's fuel cut too...I wouldnt suggest pinging it off the redline in neutral, but under load it just fuel cuts.....but if you wanna race you dont just redline it anyway, you should shift around 5800, because power drops off after that

you don't need a pic...tach signal is the green wire coming off the OBDII plug on the firewall driver side
