I was told they're needed for a/c and heater to work properly. They're like tucked into the wire loom on he passenger side.

That is correct. I just had this issue when I switched to a FAST intake and forgot to hook it back up. You wont be able to control your vents without it as they are vacuum controlled. The hose to connect to it is in the wire loom along the passenger side of the firewall.
