Completely out of ideas on how this pedal is wired! If someone has one, could you help me out?

Thanks, but as far as wiring the pedal, that diagram doesn't help me lol! Not even sure the incomplete information that is there is right! I think it's time to throw in the towel.

I added a pedal to the 98233 blue and black 165A tig welder. I bought the generic foot pedal on eBay and some multi-pin connectors on Banggood. I had to open up the pedal and swap the rheostat to a different value to match the rheostat on the front panel of the welder. Then I modified the internal wiring, running the switched contact connections and the rheostat leads through the new front panel connector. I swapped the connector on the torch switch lead to a matching new connector as well. I jumpered some pins on the torch lead connector to restore the original function when it's plugged in. When I plug in the pedal, current control goes through the pedal and the pedal has a microswitch that bypasses the torch switch. When I plug in the torch control cord, it cuts the original panel current control rheostat back into the circuit as well as the torch switch. To be honest I bought a Vulcan ProTig 200 and only use the little box without the pedal these days. I still use it occasionally but rarely hook up the pedal since I have pedal control on the Vulcan. I think it was more a vanity project just to see if I could pull it off. I was an industrial mater electrician and instrumentation technician for 30 years and I've spent the last 25 doing IT work. I can do board level repair on PC boards and have recapped hundreds of defective server motherboards so mucking around in the welder was no big deal. Considering I only paid $200 for it new in the box in 2012 and it's still working after all these years I can safely say I got my money's worth with that welder. My Chicago Electric 40A plasma cutter I bought at the same time still works like new as well.
