Tach Help (Please)

[tdogmason]

I need to find out the Tach Wire Color into the ECU for a 2004 Hayabusa. The Service Manuals do not show the color just a instrument cluster bundle. The Wiring for the Hayabusa changes all the time for some odd reason, but I am close to finishing my project, I just need some help finding the Tach Wire. Any Help would be great.

Are you changing or adding a different tach or a shift light?

No, NO2 Setup

Do a search for shift light I think you have to take the signal from # 1 ignition coil to trigger the nos, I'm thinking you are using a window activation switch?
Good luck!

Yes, a window switch it is. I'm not sure about the #1 coil I think the bike works on a two firing coil system and not a 4 at the same time. But I could be wrong. I was trying to avoid the coil and just find the Tach Wire. Thanks for the help though.
