Hi guys,
I've searched plenty, and got nowhere. My car is missing the solenoid that clamps to the cross brace and introdues extra air into the throttle body to raise the idle when the ac is on. I am interested in knowing the hose connections for that valve.
Thanks very much,
Dave

Does this help Dave? One hose goes to front of intake body and the other down to the front of the throttle body. 2-wire connector from harness as well

Great pictures! Thanks, Matt.

Some more pics for you. This is an '84 5spd just like yours.
The braided cloth vacuum hose that goes from the intake to the A/C solenoid is 9mm ID. When the hose "leaves" the solenoid, it goes to a three-way connector. From that connector to the throttle body is a larger hose. (12mm ID I think). The second hose goes over to a vacuum solenoid for the air-pump system (the pic with finger pointing).
I'm assuming a PO removed all of this and plugged off the throttle body connection?

Great pictures! Very helpful. Yes, much of my connectors have been modified either previously, or during my supercharger install.
Thanks very much, Jason,

Just a thank you follow up. The a/c solenoid was one of the items I eliminated for the supercharger install, along with eliminating non-essential vacuum connections. I found that without this valve, my idle speed was maybe 150-200 RPM less with the a/c turned on. That made it difficult to set a good idle for all conditions. Anyway, thanks to your pictures I was able to connect a simplified version of the essentially idle bypass valve, and it works great. Now, when I turn on the a/c, there is no RPM drop whatsoever. I'm glad I keep all my take-off parts.
Thanks again,
Dave
