Seeking basic wiring explanation of speedo connector block

[Hawko]

I'm going to be wiring up a Koso DB-03 hopefully in the next couple of weeks so will post up anything I work out.

Just gotta get the 'busa front end fitted first

That would be awesome I'm stuck on getting the revs to work on an aftermarket speedo


Cheers

i am starting a swap over aswell to a cheap chinese koso copy
doing lots of research before hand  and the only thing i cant figure out is where to send the 12v speed sensor (blue/yellow) as i only have an input for the speedo signal into my new clocks


quick thought - anyone know if the positive voltage is coming from the clocks down to the sensor and then sending the pulse back up
i can easily wire that sensor supply straight to a permanant positive if that is the case.

just realised it is a hall switch down in the sensormight to use the magnet reed switch they supplied with the new speedo
however the ecu still needs the speed[size=1em] sig[/size]nal, [size=1em] going to just try feeding 12 volts down the speed sensor supply wire and see what happens[/size]
i.e  R/G  connected straight to  L/Y
Any thoughts or previous experiences that have worked (will keep you updated either way for future searchers)
