Ford 3600 air filter restriction switch plumbing

[gwbeyer]

My Ford 3600 diesel is missing the air filter restriction switch. I see the nipple on the air tube that it screws onto, and the wiring is there, but where do I route the other threaded end of the switch? I haven't found any photos online showing this.

The switch screws onto the air pipe nipple and the wires connect to the switch

IIRC, the threaded end that doesn't thread into air intake is made so that the wire connector just pushes over the threads!
