Hi, all. New to the group here. I have a 2001 zx12-a2 needing an ecu and all I can find is 2000 a1 model ecu and 02-05 b1 and b2 series. The 02-05 ecu plug ins look the same. But the 2000 model does not. I know the 2000 model is unrestricted and was changed to the a2 in 2001. My question is, does anyone have an 01 model ecu or does anyone know if the 02-05 model ecu work and will I have to change the harness. Im at my wits end with this bike. Any and all help will be appreciated.
