HELP: APEXi safc in 97 420aT?

i bought my car with an APEXi SAFC that was supposedly installed. it comes on but doesnt seem to affect the fuel settings. it has a throttle signal but there is no RPM signal. the APEXi site says it will not work for n/a eclipses but have seen many people with them and working just fine. i am hoping someone will know a link to somewhere where the proper wiring diagram is. I NEED HELP! PLEASE!!

here ya go

Just remove the space between 2g and nt

You just dont see it often because there isnt a need for them, unless you are turboing your 420a, and getting bigger injectors..
