Ha!! the three wire:mad:

Yeah, your OBD2a ECU won't know what to do with a three-wire IACV, no matter how you spliced it.

I went the IACV adapter route; wished I'd bought a throttle body spacer too. Some people just block off the IACV and set the idle speed with the base idle screw. But you'll still have a CEL.

well i was reading on the three wire two 2 wire on civics but they talk about moving the pins around on the plug and that you end up with a unused 0range wire but the accord does not have a orange wire on the that plug.

I went searching too when I did my swap. This is the best explanation I found:Having lived with the 2-wire IACV adapter for nine months since the swap, the car idles perfectly, cold and hot, and I've had zero problems with the adapter or IACV.

ok I see your point but see; my f22 throttle body does not have a set screw . Is that because it was a vtec . So in other words every thing else is the same as far as sensors but the iac . On my second motor i went ahead and used the f22 intake, But this time its the f23. Hold on let me show you this ; see if it makes sense How to Hardwire an IACV Direct to ECU | eHow.com

I'm not quite sure what to make of that link. Since they're getting rid of one wire, are they wiring it so an OBD2b ECU will operate an OBD2a two-wire IACV? Can't tell.

Regardless, I don't think you're going to have any luck getting your ECU to run a three-wire IACV. Your throttle body doesn't have one of these? It's usually got yellow paint on it.

Ok you are right so instead making it any harder than what is. Ill just get that plate and be done with it:o

Yeah it does. Never paid any attention to it till you showed me that pic.

Ok so i listen to Roader i got the adapter plate its the only way to go! i guess if you do this you have to get your old IAC valve modified. in reference to the nipple that hits the tps sensor. no way around it so at work. had a 3/8 stainless steel tube bent and welded free of course; but it had to be pointing at 11 o'clock . This guy welded it at 9 it works but you will have the hose rubbing the fire wallhttps://www.hondaaccordforum.com/for...ine=1362360709https://www.hondaaccordforum.com/for...ine=1362360709https://www.hondaaccordforum.com/for...ine=1362360709

Beautiful welding! Beats the hell out of my brazed copper elbow.

Consider buying another IACV cheap at the junkard. Buy the guy at work a 12 pack, have him bend tubing into an "S" (two 90° curves), and weld that on. That way the coolant line will go over the TPS and point towards the right side of the car.
