Well a friend and I attacked the wiring problem yesterday and I have a few ?'s


Image thanks to Bense

The sensor on the middle of the intake manfiold is the idle control valve correct? It has two coolant lines, one that goes to the water neck and one to the backside of the TB. My question is that on my D series its a two wire sensor but this one is 3, what do I do about that?

Also my civic harness plugs into the big plug on the obd2 distributor. I only have the two plug left with the fat blue and the black and yellow wires. Those are for tach correct. I ordered a jumper harness but it isnt the right one. What can I do about those wires. From what I know I think I just attach the blue wire to the coil ground inside the distrubitor. What about the black and yellow wire? TIA

 

For the IACV there is no way to hook it up, I have tried every variation, and looked through numerous wiring diagrams.

As for the Dizzy, are you obd-1?

I am assuming if you are that you will need to look at a wiring diagram for the dizzy, from a obd-1 civic, to a obd-2b. I have one somewhere I will try to find it.

The balck and yellow wire I think is the crank sensor?? I am not sure. Let me check.

Ok the yellow and black wire i believe is not used. The blue wire is defintely your tach, I hooked it to the coil ground inside the dizzy.

thanks brax, so how is your idle, does it just idle at 750 even on a cold start up?

 

Yes it does, and it doesnt jump around or anything, it drives actually really good without the IACV... I dont mind, I just got the cel light because of it.

i might run my AEM, I dont think it checks for that

 

hey brax katman has an article on his site about converting a 3 wire IAC to a two but I dont see how that would benefit me...any light on this topic?

Hey, why dont you try using the IACV of a obd1 h22.

 

does the sensor look the same size and mounting etc? Anyone have any pics?
