Cooling/vacuum problem

Im kind of new to domestic cars and recently bought a 84 berlinetta. The car is in just about perfect condition except it needs some wrench time. Long story short I have broken switch that is located in the thermostat housing. If you're looking under the hood it's the right one and looks like a F. It has 2 vacuum ports on it and I can't figure out where it connects to and what the name of it is. Is there anyone out there that can help?

Sounds like the thermal vacuum switch (TVS). The following may be helpful:

Re: Cooling/vacuum problem

Is there a way to bypass the TVS?

Re: Cooling/vacuum problem

Ive been doing some looking around and most of the cars i see have 2 vacuum switches on the thermostat housing. mine has a vacuum switch on the right side of it and a electric switch on the left side and i have no idea what it is. Are the berlinettas that much different than the regular camaros? went to summitracing.com and they didnt have the switch when i narrowed it down for the berlinetta just Z/28 and reg camaro.
