question about the maft pro I got an 88 supra but the only wiring diagrams that came with my maft pro is for the 89+ I need to know what the difference is in the wiring is and what the heck is the HAC and where do I find it and so on and so forth

so then that gives me the wiring diagram but it still doesn't tell me what the HAC sensor is or what it looks like or anything else asociated with it. and if were supposed to disconect the HAC sensor then why not just cut the wire and leave it alone other than to plug the grey wire into it.
As I recall, you need to splice into the signal wire from the HAC to send a constant signal to the ECU.
