Yun Ba ATV Remote Stop Unit Wiring?

[Shawn M]

I bought the above unit but it has no wiring diagram. Can anyone help please. It has 4 wires (red, black w white, white w black and green). All it has on it is YUN BA, First Era besides that its a black box and no way of looking into it (without destroying it)

The place that sold it to me are unable to help and I could get my money back but I would rather find out what the wires did and keep it.

I know two of the wires will be 12v power but I'm sure it would smoke before I guessed the correct ones.
