ATC Pressure sensor electrical connection

I recently acquires a Tormach PCNC100. I noticed it has a pressure switch install but the wire from the switch is not connected. Can anyone tell me where it connects? I assume it’s on the ATC somewhere.

@Joe_Lustig welcome to the Tormach Forums! Hopefully this picture helps out a bit!

Actually I was looking for where it plugs into. I bought this machine used. It has an ATC put the jack on the pressure switch is jus hang loose from the pressure switch on the manifold.

@Joe_Lustig The aux jack should be right on the back of the plate.
