Bobby,
HERE is the link to the vendor at the rally. Yes, easy install using the existing wiring for the old light. You will have to drill at least one new hole for mounting. It's been a couple years but I think I drilled all new mounting holes. It seemed to be a good idea at the time but I don't remember why. Coil n Wrap has a better price too.
On edit, the supplied LED bulb lasts a very very very long time.
