Hi,

You can use evry wiring harnes of rc51. They are all equal.
Also you can use the sp1 injection for sp2 engine. The only thing you
Need is the right ecu.

i thought the sp2 had an extra fan though and another plug on the thermostat would you just not use these ?

Good response,

I learned from first hand experience though that on a streetbike the SP1 ECU is "no bueno" on an SP2. It took me a while to figure out with the help of others and signal tracing that I had an SP1 ECU.
