Maya PM 30 Min- Claw Machine

I'm trying to figure out which pins are which on the giant gantry, so I took a few male-female wires and a Multimeter to try to read which wire was which based on their resistance as directed by Mr. Burnham and it was pretty inconclusive. Maybe it was the way I was trying to hold the pins while measuring, but it was pretty inconclusive because the measurements jumped wildly and settled down onto a number around 5, which doesn't seen correct. I'm also taking some time to look up the stepper motor's code so I can complete more of the Logic tree that I made along with the code.
