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?

here is a pic

The two you have on the truck are for the tail and the turn/brake. You don't have a wire for the ground because the factory stuff gets the ground from the metal bracket. Just ground the wire to metal and hook up the other two to the existing wires.
