Here is the diagrams. You will need to switch to a Y8 or Z6 manifold with a 2 wire IAC. http://www.turbod16.com/viewtopic.php?t=3572

Re: obd2>obd1 conversion
 

csaddict- your link says all AT vtec, and non vtec cars use a 3 wire. does this mean his dog-o-matic? Y8 has a 2 wire? ---- obdII

Re: obd2>obd1 conversion
 

just unplug it and look at the wires and you'll know either 2 or 3

lol

Re: obd2>obd1 conversion
 

Automatic Y8's have a three wire IACV. Even more of a problem is going to be the fact that you have an auto car and the ecu harness has 4 plugs and an auto p28 ecu only has a place for 3. So you plug it all in minus that plug and your all happy that it starts up, but your gonna be really pissed when you try to drive it and the damn thing will not let you shift out of park. Without that fourth plug, plugged into the ecu, you have no auto tranny functions. But that is ok, your sort of in luck, cause there is a company that now makes an OBD2 -> OBD1 "AUTO" conversion harness. Check out http://www.rywire.com/store/product_...products_id=57 It's not a cheap conversion harness, but sometimes you have to pay to play. Ok, so now your happy cause you got it all figured out, you just have to do the 3 wire to 2 wire conversion on the IACV, BUT WAIT!!! there is no spot to mount the 2 wire IACV on the auto Y8 intake manifold because the auto one is on the throttle body :o So what's the answer to this one you ask....well, it's Thanksgiving, not Christmas and I am not gonna tell you everything. Why is everyone spoonfeeding you info? I have no idea and it is actually blowing my mind. :S





Oh switch to a maual Y8 intake.....Merry Christmas fucker!!

Re: obd2>obd1 conversion
 

hell id drill some holes in it and mount the y8 IACV on it lol

Re: obd2>obd1 conversion
 

You do know where the holes are located right? They have to line up with the throttle body and it is bored at an angle. I say let him send you the manifold and if you can get them to line up properly and tap the holes and all that jazz, then go get your motor back from your builder and assemble that fucker yourself, LOL ;) Seriously, it might be something that is doable, but it is not going to be as simple as picking up a drill and making some holes. Not IMO anyway.

*edit* I guess if you had an old TB you could bolt on and use it as a guide for the one hole that is angled it might help.

His car is a stick, i would NEVER put a turbo on an auto car. Unless it was a GN.

Re: obd2>obd1 conversion
 

So WTF does this mean then, sounds like to me your asking if his auto Y8 has a 2 wire IACV ::)

Re: obd2>obd1 conversion
 

OHHH i get it now. I didnt know what dog-o-matic meant. It means AUTOmatic. Yea on the link it said that auto's and non vtecs used a 3 wire, but it didnt say what the MT cars used. Were good now, thanks to all that helped ;)
