Name that vacuum port!

Sorry...new to this forum but I've come to like it for lurking purposes the bestest...

Weber-Nuttered 4.2 in an 88. I was cleaning up some vacuum lines and found this on the back of the engine near the firewall sucking away like a feind with nothing attached to it. Should it and to where?
Gracias!

I believe that is the one that used to be hooked to the decel valve, which you don't have anymore. So you can cap it.

I thought that one is for the vacuum line to the heater control box.

Goes to the heater control for the passenger side vent. The line actually goes through the firewall to the heater vent control switches. If you don't plan to use the right side vent then just plug the hole. To get it working do some searches for heater vacuum control as there are other parts you might be missing such as a check valve and small vacuum line.

Isn't a jeep one big vent? That explains my pain below 10F!
