After locating an owners manual online for a 2009 I've found that the mystery button is a reset button. I guess in 2009 they moved the reset button from the right handle bar to the button on the console . Why, I don't know.
This explains why the plugs are different. After studying the wiring diagrams, I cut the plugs off the wires and connected the wires with bullet connectors so now all my dash functions work .
Although I still have to deal with the button since my console has no hole for it .
I don't know if this thread will ever help someone else but it helped me.
