Led taillight wiring help

[MandarinSixSeven]

Hey guys, i just went out and bought one of these lights to see if it would work on the ol truck. It looks like its a taillight for a big truck or something, but I think it would look pretty cool on the stepside. Now I need some help or suggestions as to how i should try to wire them up.. they have 3 wires, one ground (white) one tail (red) and one turn and signal(white) but my tail lights only have two wires....how the heck do you wire it up?
