Powermax 30 wiring

Trying to wire torch up so I can hook it up to my new Pro. Found the 3 wire connector that said “torch start” . Ohming it out there was two wires that had continuity. When I press the trigger all 3 wires show continuity. What is the answer to this problem. Lol!!:grinning:

Cap Sensor Switch.

wiring diagram is the last page of the pdf.
