Hey guys, I have been searching and looking for an answer, found nothing so decided to do some research on what I am trying to do...

Basically I am trying to figure out exactly how to hook up my vacuum hoses/sensors for my swap which I am trying to get bar'd legal.

Yes I searched and know that you can cap sensors blah blah blah, but I'm trying to go the correct route and get it going without throwing codes and what not.

NOW, the big thing is that stock which I have a 1990 EX sedan (MPFI STOCK) and the firewall sensors have only 2 wires, where as the Integra firewall sensors have four... Now according to my research looking up pinouts and how to go about wiring this up, A10 would be where I need to wire up the green/yellow wire on the sensor.

BUT my problem lies in the Purge Cut Solenoid Valve... For this sensor, I can't find where on the ECU it is supposed to connect... The only thing that I do know is that it is a green wire coming off of the ECU which doesn't help much, because I don't know what pin that would be...

I have searched high and low with no solution, even a wiring diagram that doesn't give me the ECU pin #, it just tells me that this wire goes to the ECM. The only way that I can think of figuring this out if no one here can help me out is to head over to my friends house and get out a volt meter to find continuity. That is my last resort.

So does anyone know what pin # is for the Purge Cut Solenoid Valve on the obd0 PR4?

Here are my sources of info...

Thanks for anyone that can provide me with help so I can get this car legalized!

 

so nobody?

Does anyone have a pic like this for the pinouts of a 90-93 Integra??

this might help with the wiring. it's a diagram for a 90-93 integra

 

You dont need that green wire is useless, as a matter of fact u dont need a purge control solenoid just leave it unpluged or get the pin out of ur ecu, ive got a obd 0 b16 without it and the car run just fine, and depending on where u like u dont need a charcoal cannister so get rid of that too. just plug the map sensor and tap the vaccum pot that goes to.

 

I got that manual, well the wiring from 90-91 and 92-93 is different now that I think about it, which that manual has wiring for 92-93 OBD1

Read much? I need to connect it to pass emissions in California. Either way I would want to connect it because the smog in California is bad enough, and I'm not one to add to the problem.

 

sorry, i didn't go through the whole thing to see if they did a separate one for the obd0 and obd1. i just saw that it said 90-93 and assumed they did. well good luck man.

 

Thanks bro I appreciate you trying to help. I didn't realize it until later on when I found a different manual that was better than the one you posted but it was OBD1 which places the wire that I am looking for at pin A20 which there are only 18 pins on OBD0. So I didn't know that there were different pins until I found that out.

^^^^^^^
I dont know what u tried to said with that(read much)?This is what i get for trying to help, ungrateful h-t'ers, sorry that u live in a suck *** emission control state,You r welcome anyway!

 

You were of zero help to my issue. This was my second sentence of my FIRST post... "Basically I am trying to figure out exactly how to hook up my vacuum hoses/sensors for my swap which I am trying to get bar'd legal."

Try reading that again, especially what I put in bold for you. I don't expect you to reply though as my issue is solved, I went and manually searched for the wire with a continuity meter and figured out the pin number. Which are pins A6 and A10. I just figured someone here might have known and I wouldn't need to bug my friend to let me rip his carpet and ECU out to test for a wire.

You really should go back to school and take some English lessons though... "what you tried to said." "The car run just fine." Come on, we aren't in grade school here, I think you are capable of writing better than that buddy.
