Powermax 380 Wiring for Pro Table with THC

I am a current OG table owner with a pro on the way. Unfortunately with all the Hypertherm cutters on back order id like to use my old powermax380 until the 45 arrives (20 weeks they say). Does anyone know where to find wiring instructions, my understanding is the trigger control is easier and you need to pull the arc signal off the ground wiring for the THC?

Note I’m keeping the OG table at my house so can’t steal the cutter from it.

Thanks in advance
