Cruise Control vacuum
Anyone have a vacuum diagram for the CC on a 91 firebird trans am? I have one hose that deteriorated badly and I can't figure out where it goes.
I will try and post a photo later. Thanks. Mark

Re: Cruise Control vacuum
You didn’t mention which engine, but here's a diagram for a 91 camaro TPI. Source comes from Passenger rear of manifold. At the metal fitting. It T’s off at the vacuum ball reservoir.
The larger hose goes to the brake switch under the dash. Or clutch switch if you have a T5
