Then generally the white wire is the 12v side of the coil [ignition on] and can be used to power the 12v to tach as well
So it all revolves around the coil!!!
Check your Wiring Diagram to ensure you are attaching the triggers to Trigger side of Coil...all set!!!
Note; I believe that Fuel Injected Models are Single Fire, and therefor require a different Tach... Ensure you get the Correct Tach for your Model... which I believe is Dual Fire... But I am Not familiar with anything very new!!!!
Darn... I think I found a Wiring diagram for your 2003... shows dual Plugs...and seems to be Single fire.. Shop accordingly if this is yours!!!!

It is as simple as attaching trigger input to tach to the Trigger side of the coil...
