Hi guys, as noted in my other thread "FIERO JOURNEY", I am making a road trip from IA to CA in only a few days. I have some extra vac hose lying around, and I noticed that both of the Vac ports on the cruise control dealie are missing. Mysteriously, my cruise control worked when I got my car in august, but quit about a week after I got it, and that was when I noticed the vac lines were totally missing.

Where exactly do the Vac Lines going from the cruise control coffee can connect to?
Photos would be EXTREMELY appreciated!!

Thanks much!

No pics, here's a description that should get you there.

The two vacuum lines that run acros the engine-side of the trunk firewall, the smaller, upper one is the charcoal canister purge line and it also doubles as the vacuum source for the cruise system. The larger, lower of the two steel lines is the ported vacuum system from the throttle body that is used to modulate the charcoal canister purge valve to control when the canister is purged and how much.

On the cruise vacuum line routing, the upper, larger port on the vacuum servo goes to the vacuum vent solenoid (with the red 2-wire connector), the lower, smaller port on the vacuum servo goes to the smaller port on the vacuum canister. The larger port on the canister goes to the tee in the metal vacuum line.

Ok so start at the solenoid valve ( has red plug) , hose goes from solenoid to bigger fitting on cruise control device.
Little fritting on cruise control device goes to the little fitting on the vacuum canister.
Big fitting on vacuum canister goes to the metal vacuum line attached to the back firewall. Hope that helps.
