i have a 92 prelude and have swapped a jdm h22 type s into my car. the car is obd1 and the engine is obd2. we swapped all the parts out to make the engine an obd1 engine except the idle air control sensor. it is located on the back of the iintake mainfold and the intake mainfold is the euro-r manifold... or very similair.... the thing is the obd2 sensor is a 3 wire conection and we need it to be a 2 wire so it will work. i could really use some help. is there just a different iac sensor thag is 2 wire i can get that will bolt up in place of the one thats there now or is there anything else i could do?

 

The car will idle very high with the 3 wire iac.i modified a 2 wire to work i on this same engine.do a search on here,i found a couple writeups that helped me a couple years back."search archived"
