If you bought the gauges from me...They should have come with at least generic instructions (Some models have step by step)
When wiring.....There are some rules you need to follow.....
NEVER WIRE TO A HEADLIGHT!!
Now we can move on.........I installed them on my 2000 ZX12R
The wiring is very simple for most sportbikes......
98-99 ZX9R, Correct me if I am wrong, has a little running lite or lite up in front upper right????? That is all the power the Illumiglo Gauges need to run.....2 wires, splice it in....You are done.
Any questions...Let me know....Will help you as much as I can.
