CHEVROLET LUMINA CRUISE CONTROL PROBLEM

1991 Chevrolet Lumina • 291,868 miles

Hello, I just finished rebuilding my 1991 Chevy Lumina motor. The car runs great, I have already put about 250 miles on it. I need a vacuum hose rounting diegram for my cars' engine (3.1 Liter V6 Motor). The car's heater, A/C, Cruise Control worked fine before the car broke down. My repair manual said that the Cruise Control and the Heater & A/C Control Assembly are CONTROLLED by vacuum. My guess is that I must of not hooked up a vacuum line right. Can you PLEASE help me with this problem? Need a Vacuum Hose Rounting Diegram. Thank You.

There is a hose that comes from the firewall that goes to a vacuum outlet by the alternator on the upper intake. It faces the back of the motor behind the power steering pump.
