Ok razorweld 30i showed up need help

I cant find the vid to show how to wire up the torch fire cable to my razorweld 30i

Using a volt meter on ohms put the 2 thingys. red n black on 2 pins on the torch cable at the plug that goes into the machine. pull trigger if it shows ohms its them 2 wires. I beleive it will be the top 2 wires on the plug that is on the cutter. Mine was and my neighbors. Take cover off of cutter to tap into them 2 wires in it.

I will pop up the post with a vid on how to . it will be on the 30i torch wiring
