Newbie here with an interface question. I just purchased the Tornado Spinner from SlikStik with the new Mini-Pac/Opti-Pac interface cable and I need help hooking it up to the Opti-Pac. The spinner has four cables connected at the end with a small red connector which I'm assuming is to connect it to the Min-Pac. I'm guessing I have to cut off the connector and plug each wire into the corresponding spot on the Opti-Pac. The problem I have is I don't know what the wires are. The wires are black, yellow, green, and purple and I'm guessing one is ground, one is 5v, one is X1/Y1, and one is X2/Y2 can anyone tell me what wire is what? Thanks for the help.
