Acewell Speedometer

[Lord Popgun]

If your bike is a '14 or later, there is a serial data bus that is going to come into play. If your new meter doesn't play with that you are going to have more problems. Speed data is sent from the speedometer to the ECU on this buss. Data actually flows both ways as it is a bi-directional serial data bus.

I can't see your pic at work and don't have my service manual here so will have to wait til later to help. Hopefully Max and Peterbaron or Powerdubs will jump in but I'm not sure I'd want to kludge it up. Honestly, I think replacing it with OEM is a much better idea. Especially if you have ABS.
