Have a hose pipe that I believe leads from the Air Control Check Valve, but I don't know what it would have run to. When I got the car the air pump was already off and hoses where capped off with lug nuts .

The line coming off the AC/CV is the one circled with my mad tyte Photoshop skillz








I'm trying to figure out where I can/should hook that up to, or it would be ok left open, or I should just cap it somehow. I do have the air pump, but as is, it's sitting in the trunk at the moment.
