Can you still see the vacuum hose diagram on the underside of hood?
thanks for the quick response to my question. i don't see any vac hose diagram under hood.
Look around, it was one there once upon a time! Do you see any labels at all? Look again! Looks like a bunch of black lines on a white label, or vice versa.
Which engine? 4 or 6 cyl.? And do you see the hose at all? You ask where it connects to the eng. so do you see the hose? Repair shop is where you need yo go.
