on my 90 ls motor that I put in my 88 hatch had a double vacuum solenoid that is mounted on the firewall. Originally it had one regulator control solenoid valve on the civic. But for the integra motor it has one called purge cut solenoid valve that goes to the pressure regulator on the fuel rail. There are two wires coming off the solenoid(one green w/ yellow strip, and one yellow w/ brown stripe) where do these wires need to be connected to.

 

anybody have anything??

 

Ok, Use the stock solenoid valve on the firewall. Route a vacuum line from the bottom of the valve to a "T" which then goes to both the FPR and the back of the IM. Leave the top of the soleniod valve going to the cannister. and use some sort of plug on the other fittig in the IM (the other one that went to one of the valves). Let me know if you dont understand (kind of confusing w/o pics).

I tried using a T on the upper part of the valve which went to the FPR and the cannister. It seemed to run the same.

if you want to add the FPR solenoid valve one of those wires goes to A10 (thats what it says here > http://www.hasport.com/Tech/Wring/Co...1%20DX-SiR.htm), and the other probably goes to ground. Get an integra chiltons manual (best wiring diags, and it'll be usefull anyway) and look which one goes where.

Thanks for the help Ben.
