Decided to hook up a clear alternatives taillight tonight and having a hard time. When hooking up the wires from the tailight itself there are 3 wires (red, green & black, assume ground wire?). The wires from the bike are black, black with yellow stripe and black with white stripe. Hate to sound too dumb but I am unable to tell which of the striped wires are positive or negative and I hate to get it wrong and possibly blow the LED lights in the taillight? Couldn't find the info on either the Clear Alternatives website or Mad Mardigens site that has a nice piece on CBR1000 mods. Thanks in advance for any help!
