The black ground doesn't connect to the switch.

It usually connects to a terminal strip. And is used as a ground (neg) for the gauges and accessories.

I do not have a blue wire. I have as follows

Black
Yellow/black stripe
Red/purple stripe
Purple
Black/yellow stripe
Yellow/red stripe

The Black/yellow stripe there are 2 and they are together. If I dont hook up the black I have an extra terminal on switch.

Sounds like someone replaced a wire.
