Next you'll need to map each of the wires using continuity mode on a volt-ohm meter.



Touching one meter probe on each wire, locate a map the pin locations on the end of each connector.

Take your time on this step. This is a "measure twice and cut once" job that insures your controllers will work correctly.



Also: Don't depend on the colors of the wires!

Red doesn't always mean positive. Black doesn't always mean negative.



I've included a worksheet on this step which you can use to map each wire.

(I've also included a copy of my own worksheet so that you can see just how strange the color codes can be.)



Using the blank worksheet, write down the color of each wire as you find it's position in the connectors with your meter.
