that to bypass it, if it works unplugged, from the harness and the vac line the boost solenoid is bad.
you can just pull the vac line off it, and jam a golf Tee or stick in the line to cap it. watch the line end, well check it for cracks when you take it off, they get real hard, and brittle and snap when pulled off over the hump on the vac port.
a 2 inch new piece of vac line will replace the factory end, just use a razor to cut it off the plastic line. most auto parts stores will not charge you for 2 inches of vac line, so just ask for it. stuff is cheap, cents per foot. maybe 10 cents if they charge you?
