All of my units came with 3 wire harnesses. If anyone wants to skip on the ground, thats up to the individual. I havent personally openned up any of the units but usually the ground is normally wired to the casing no?
In anycase, ymmv. if your cord came with two wires, then use a two prong power cord, otherwise use 3 if it has a ground wire. This should be pretty obvious.
