What Is This?
This is on my firewall by my brake booster. It has a Vac line on one side and wires on the other. Thanks

Re: What Is This?
Weird...my 80 C10 doesn't have that... I wonder if it has to do with yours being a 4 wheel drive

Re: What Is This?
that is the vacuum switch for the TCC. WHen it senses a loat, it will disengage the TCC.

My next dumb question... Should this vac line go to manifold vacuum, like where the vac line goes for the transmission? I failed to mark this one when I pulled the motor.  Thanks again!!

Re: What Is This?
If the turbo 350 is a pre 81 its not a TCC trans and its not needed.
