Still working on this? I had that euro switch on my '07 S4Rs until quite recently. Yes, it was plug and play. I just returned mine to stock; have the euro switch on my workbench, lengthening the wiring to go on my DS1000SS roadster project. I can post photos if they will help. (Euro switch below looks smaller because of the closeup photo, they are identical in size.)

I'm kind of working on it. I have it wired up right now so it works but it's not how it was stock. I was trying to get a pic of the bike's main wiring harness connector that connects to that switch. My bike doesn't have all the wires coming out of it to make it truly plug and play.
Thanks for letting me know it is plug and play. I think I can now say for certain my wiring harness was modified. Maybe someday if I strip the bike down to have the frame repainted I'll buy a new harness.
