I have a 87 Camaro 2.8L MPFI it has a double vacuum port on rear of upper plenum I know the large port is for the brake booster, I have a vacuum hose from the cannister in the left front fender and a very small short plastic line at the heater/a/c box coming out of the firewall I think both are for the heater controls but I need to know what type of connector marries them to each other and the port. The car was disassembled when I got it and pieces were missing.

 

I posted on your other thread.
