okay so I have a 94 Acura integra Ls 5 speed manual, and I'm putting a jdm gsr into the car. I only have a p72-901 auto ecu that came with the motor, as far as the Acura dealer and other sources say that it can be used for my 5 speed, and pinout will be the same as the p72-ao1. So with that being said, this helpful link https://honda-tech.com/forums/honda-civic-del-sol-1992-2000-1/92-00-honda-engine-swap-wiring-guide-vtec-non-vtec-2987229/ shows how to hook up vtec, IAB, oxygen sensor and k-sensor. But when I look at plug a on my harness it has a red wire coming out we're the IAB should go. I will apologize in advance if this has been covered and I just couldn't find anything regarding this. All other things that need to be wired in have empty spots where they should go, this is the only one that has a wire in the spot. The red wire per the Acura manual is the evap purge control solenoid valve. If anyone can help shine some light on this that would be great!
