Somehow the motor decided to spin (I was being stupid and pushed the wrong buttons) and the probe wire snapped at the plug end. Fortunately, no other damage is evident. I'd like to solder in a new plug. The wire seems to have 2 leads, a white inside wire, and the outside copper shield mesh. (I only see two leads, yet curiously the molex end of the patch cable has 4 pins.)

I'm guessing that the patch cable jack accepts a 2.5mm aka 3/32" audio plug, as used with cell/radio phone headsets. The local radio shack only had a stereo plug, but I'm guessing that I can use it by soldering the white wire to the tip, and the copper shield to the sleeve (barrel) of the plug, as well as to the ring for good measure.

Can someone please confirm or correct my guesses?

Thanks,
