The port on the drivers front is probably for vac. operated choke or cold start canister. On the backside bottom should be port for vac. modulator on tranny.

And I think the one on the backside at the top went to air valve in the stock air cleaner.

The one on the back topside by the air valve went to the hot air choke (source for filtered air).
