vaccum help

[adamforsythe]

Hello,
I just got the tranny and engine into my '86 blazer. I have about 90% of everything hooked up. But behind the carb there is a T valve/fitting one of the vaccum hoses that run from that goes down to the tranny. But where does the smaller one go? I think on the old engine that was in the truck ran to the carb. But in my '85 there was a small tube the ran from the fire wall and hooked up to it.

hook up the line from the firewall to it, that is how the heater changes vent/floor/defrost

The only line that is coming from the firewall has wires in it. But it is coming from the same place that the hose came out on my '85 that hooked up to that T valve. Should I hook it up and see what happens?
Thanks
