I just received a CM20(MRC) walkaround throttle. In the directions it shows 4 wires. I'm sure that is for a telephone plug reference, right? I just have 2 wires(+ & -) & can't figure out what to use the other 2 wires for. I'm going to use a single prong electronics plug for all the connectors at the diff. locations.
How hard is it to use the phone 4 wire plugs? Do U think I might have trouble w/trying to move them all the time from plug to plug?
I know this topic was up before, but couldn't find it on the forum topic list.

Hi Larry, is it possible that a power supply is (Base unit, source) to be used with the hand held unit?
It would make more sense that way.
1/ Source voltage 2/ common 3/ speed 4/ Forward and reverse
Just an idea :D
