Gear Indicator fitting problem - HELP PLEASE?!?! 
  Gear Indicator fitting problem - HELP PLEASE?!?! 
 
 -------------------------------------------------------------------------
 
 I'm trying to fit a Biketronix gear indicator to my 1098 with a lot of frustration and expletives yet without much success at present --- arrgghh!
 
 All I need (sounds simple, I hope it is) is to know which colour wire either at the rear of the speedo or the ECU is the 'tacho / pulse' wire...
 
 Anyone out there who can help me please? I even have the wiring diagram, but am still not the wiser.
