Hi folks. I have a sweet Topaz 4-door 1976 SAAB 99 GL. Outside the main engine compartment, on the back of the wheel well on the driver's side (USA), there is a device with two hoses coming and going, and an electrical contact. Two of the hoses are 7/32 vacuum hoses. They go through the engine wall and one connects to the 11/32 hose splitter on the booster grommet but the other one is just dangling. Any thoughts?
