i know one of the lines (small) goes to the vacuum ball. the big one goes to the brack pedal switch. i have a couple a check valves that are suppose to go to it also but do not know where they go.

 

I just began to work on my 92 Camaro RS cruise control system. I discovered the vacuum ball was removed by the previous owner so I bought a new one and replaced all the vacuum hoses because they were too old to function. I'm waiting for the speed nuts and screw so I can attach the ball into the car.
