pedretti_gaming thanks for your help! We still have a couple questions. There's some confusion - the connector is 9-pin but the wires are on pins 2, 3, 4, 5. Pin 3 is a key. Is it possible this mod we bought has the connector wired in reverse? Can somebody give me the correct pinout and what each colored wire is for? Does the alligator clip supply 5 volts?
Thanks so much for your help!!
