Brake pressure dash buzzer

I'm in a 2010 international 4300 with hyd brakes. Everything checks out fine but this buzzer is constantly going off! Work says truck is fine. I've got a headache and this buzzer keeps going off. I'm ready to shoot the dash... Where is this buzzer location so I can rip it out until I get home at the end of the week?

 

Mechanics say everything checks out fine. Went through all the electrical and nothing seems to be triggering the alarm itself. They think its a sensor malfunction. However, it can't be fixed until I get back to my home mechanics. Which I won't arrive there until Wednesday night. All I want to do is snip the alarm so I can sleep. Too hot out for the truck not to be running with AC going.

 

I'll give it a shot. Thanks!
