I know it wasn't supposed to work, but I ignored what I thought I knew about electrical wiring and it worked. After going to Napa and getting dual sockets I realized that is what I had. The NAPA sockets also had two black wires coming off them, but obviously you can't have two grounds. So I connected the two live wires from the wiring harness to the two wires on the light and I wrapped the ground from the wiring harness around the mounting screw on the housing...and voila...everything works like it should.

And nothing caught on fire. Did I mention I hate wiring.

Thank you for all of your help.
