I have heard that there COULD be a minor difference between obd1 p72s, and obd2 p72s. In obd1 i believe the ecu sends a 12v signal to the IABs, and in some of the obd2, the ecu sends a ground.

Is there any truth to that? Have any of you ever run into a situation where an obd1 p72 does not properly run the iabs on an obd2 motor?

sorry if thats a stupid question, but inquiring minds want to know

edit: my car is a 2000 gsr, obd2b for you kids not in the know. i am acquiring an obd1 p72... and i just want to clear the air about whether or not it will run iab's correctly
