unless im mistaken these are the colors to look for.
solid green: thats your ground. hook it up to the frame/casing/whatever of the light. or if it has a tab for a ground put it there.
1 brown wire and 1 green with yellow stripe: these are your power to the tail light and the brake light (its a dual filament bulb) there are 2 wires going to the light bulb itself hook these up to those. i forget which is which though.
hope that helps.
