Ported Vacuum Switch

[justacruzr2]

How do I determine which ported vacuum switch is the correct one. They list 5 different ones in the catalog.

Dark Blue; 2 Ports
Black Finish; 2 Ports
Purple; 2 Ports
Blue; 2 Ports
Black; 2 Ports

I'm thinking the difference is the temperature at which it opens. Anybody got any clues?

This is the ported vacuum switch on the thermostat housing. It's an 84 GP w/305.

Is it for the EGR or something else? What do the hoses go to?

I'll give this a look tomorrow. Have been way too busy at work today. Meanwhile, thanks for your replys.
