need help w tps

ok. so my friend has a early 90's 3kgt.

he got the generic zex dry-shot nitrous kit.

its all ready to go except i dont know which wire on his mass air / throttle body is the throttle position sensor.

ne help would be greatly appreciated. we just finished completely rebuilding his motor after he siezed it via water in the CAI and hes very anxious to be able to beat my car.

also any applicable links would be great too.

I've never put the stuff on my cars. Do a search on www.3si.org (http://www.3si.org) and you're bound to find an answer.

thanks for the link.

someone has to know though. PLEASE!
