Where is the Air pressure switch for low air buzzer?

Hey y'all, I was wondering where the air pressure switch for the low air buzzer is on the deuce. The low air buzzer hasn't worked the entire time we've had the truck (little more than a year).

It’s up underneath the dash. If you follow the air lines in the engine compartment to the firewall, there is a bulkhead connector T. On the other side of that is the switch and some lines. Be careful taking it out. It’s easy to turn the bulkhead connector and bend your lines. Is your buzzer plugged in? Mine was unplugged. When I plugged it back in I discovered the switch was stuck on so the buzzer never stopped. And it’s loud! No wonder folks leave them unplugged.

It is plugged in. Which is why I think it's the air switch but I'll probably disconnect it to clean the connectors. But thank y'all for the help. I'll get to it as soon as possible.
