Does anyone find these things helpful? I just got myself a Digital Gear Indicator by Datatool a few weeks ago. It doesn't have the factory harness and I was just curious if anyone had installed these before (i.e. are they a huge pain in the @ss to install). I own an '01 GSXR 1K and haven't taken the time to install it yet. Does anyone have a link or can email me some pages with the factory wiring diagrams for my bike? That would be extremely helpful. Also some good installation tips or persoanal experiences would be great to hear.
