What year is your car, what motor? It looks like by the picture it would be for the smog pump but we need more info.

well I don't kow exactly what it is but I'm pretty sure it's emmissions related. If you have the end of it that's pictured, the other end might go into the factory wireloom. I'm guessing it runs across the engine or firewall. Does it run OK and does everyting work normally? Any Check engine light?

Does that thing have heater hoses going to it? If so that is the heater control valve and the vacuum lines goes back to the firewall somewhere.
