Thanks for this info Pilbara. I got the switch with my bike ('07 990) and it never worked. Only the Mode button and the Minus button would work.
So the dealer shipped me another one, and I connected it today, with the same results. Now I'll have to go back in there and see if I can trace the wires and see if it matches the diagrams that you have posted.
One thing that I'm not clear on though. You mention a special tool and crimps. Is it not possible to just move the wires on the speedo? I've never attempted this kind of thing so I'm wondering if it's over my head.
Next time I'm in there I'll be sure and take pictures and note the wire colors too.
