Motorcycle Repair: headlight wireing, high intensity, harley davidson

Question
i bought a new headlight and it has 4 wires and the motorcycle has 3.2 wires are the same color.how do i hook it up.the bike is a harley davidson super glide 2010.

Answer
Tom If the headlight is OEM it will have 3 wires. If the headlight is aftermarket such as a HDI high intensity blue light there is a extra relay and fuse that has to be installed with it.Otherwise you may not have all the components to make this work.
