Left goes to secondary vacuum canister (looks like a toilet bowl float). Middle line goes to the tranny. Right line goes to a nipple below the EGR, I think to the intake manifold. I cannot see this connection, but that is where the old one went when I replaced it.

As for the "silver" box on the driver's side fender well, there is a box on it, but it is black. Has some vacuum lines and wires attached to it. I will try to get you a picture of it, but I think it can be seen in one of my earlier picture, maybe on the previous page.

 

Any thing here guys? Been searching all over for this answer

 

What is your question? This thread you replied to is almost 7 years old. Why don't you start a new thread, tell us what truck/engine you have, and what your problem is.

 

And is 4 pages long, nobody is going to read through history like that to try and figure out what you're talking about....

 

Sorry I totally didn't mean to write it so vague. I have my vacuums run wrong and I know it. I saved your info from the 3 holes in the firewall but what else goes where. I'm a TOTAL noob. I have a carb and air cleaner with lots of screws in hose lol
