[V8] 5sp throttle body question

[toml99 at todomundo.com]

Hey Ron, I only see 3 things in the pic that sound like what you are  
talking about.  Large drivers side hose is the front breather hose,  
and runs to the rear of that head.  The 2 on the passenger side go to  
the "frequency valve" that goes to the charcoal canister.  I only  
know the last part because I saw it on the vacuum hose routing  
sticker under the hood  ;-)
