My switch seems correct. It is the same one that you had pictured, except DPDT. I just used one side of the switch.

I will try to check the ground connection today. I have the ground attached to my intake manifold. I also have to note that I use the same ground for my grounding kit. Would this be affecting it?
Good man!! Those are fine numbers. My switch is actually DPDT too - a little clever photography hid the other pins

I'm guessing that your ground is the issue and your continuity test will tell you for sure - the intake is subjected to a fair amount of potentially corrosive road grime, and unless it's painted or cleared, the aluminum will develop a layer of surface oxidation that could prevent a good connection. Otherwise it should be a fine ground - especially if the grounding kits recommend it.
That said, I grounded to the factory grounds located to the rear of the driver's front strut tower. It was tidier looking, and required less wire.
