Vacuum line to this?

[nightrider50]

Got the whole motor back together and missing one vacuum connection. Did some searching and found some really good vacuum diagrams. Only problem is... I don't know what this unit is called. Anyone know what, if anything, hooks up to this right next to the electrical connection?

if that car has a mass air meter DO NOT put vacuum line to that.That is a barometric meter,and must read barometric pressure.If the car is speed density it is hooked up to intake manifold.

Perfect. Car used to be SD and now is mass air, probably what threw me off. Thanks

+1, that's barometric pressure sensor.
