I am still putting tuned port on my car which i took off of an 89 IROC. Anyways the vats thing is killing me so i bought a vats eliminator harness from painless..... Problem solved.. heck no....... Directions from painless says to plug the one wire into the f or f10 terminal....i look on the ECM and all i see is A,B,C, or D. Anyone ever hook one of these things up before?.... Does the elininator hook up to the ECM or am i missing something ??.... Everything is done except this... 2 months and counting... Anyone have an idea??

 

How many wires does the eliminator have? If it is a three wire unit, 12V, ground and a third wire then it will most likely go to the ECM. I am using aftermarket manuals but my one book shows the signal going to terminal B6 on the ECM. It should be a 50Hz square wave signal. If you need more help try to post the wiring diagram from the unit and I'll try to walk you through it.
