It connects directly into the multi plug connector behind the water filler next to the air box. Wires are pink / white and pink / black, any ideas very welcome, Fraz 8DE5B4A9-2752-47DA-A93D-6ABC78C49E3A.jpeg 87D39B6C-BAA0-4C38-842A-EC5877990D0B.jpeg 247EBB6E-D543-45ED-B10A-07F1E78D8E76.jpeg

    What year is the bike?

    Get out your wiring diagram, see what part of the electrical system it's attached to, and you should have your answer. Since you gave its location, see below.

    Often people wire-up their thermostat for the fan on water-cooled bikes to override the thermocouple, so they can turn-on the fan earlier than the thermocouple would. Does the radiator fan come-on when you turn on the key? Switch-off the switch you have there, and see if it cuts power to the fan. Is the thermocouple by the thermostat unplugged?

    That is what your stock Run/Kill switch is connected to normally (the red/white and red/black). My guess is the stock switch was failing (not too uncommon) and this was the "fix".

    Following up with what one2dmax (Sean) maybe a somewhat hidden, redundant kill switch for security?

    I was thinking ejector seat, oil slick, rockets, machine gun, banana peal? Lol. Well I guess we can't live Mario Cart.

    KITACO make's aftermarket stuff,Chinese. Do you have a stock speedo?
    Go to their website and do a product search for something/kit with that switch.

    Thanks everyone, lots of ideas, nothing turns off or on with the switch that I can see. Judging by the ware on the front tyres and set up of the bike I’d say it’s been raced so could in fact be NOS or v boost overide, I’ll post any findings, thanks

    What rpm does vboost come in at? should be 6000rpm at I'm sure you know. Could be a crude vboost mod.

    As one2d pointed out the wiring is allegedly for the kill switch. Original one still works and disconnected the kitaco one and no difference whatsoever, still baffled. On another note the water pipe from pump to thermostat was tye wrapped in with a bit of rubber at the pump end. Fitted a new pipe and when it gets to pressure it starts to push the pipe out. Probably why the mod in the first place. Going to seal it but wondered if it’s indicative of another problem?

    Haven’t checked the vboost yet woodsy but will when I’m happy with the water pipe
