Help!
 

I was checking under the hood the other day and noticed a hose coming off my efi with a bolt in the end. I've been looking around and i'm pretty sure it has something to do with my cruise control(which doesn't work). I don't what the part looks like but i saw something similar to what i think it is. It's a circle brass colored piece. I was hoping someone with close to the same year (89) could take a pic of their efi so i can see how it is supposed to look. Also, if anyone could tell me what its called.
