im new on bike i have cbr f4i 2003 i need new wiring my bad my 03 n found guy have 04 is all the same ? n 04 seats fit on 03 bike ?? thanks for help

 

Wiring is the same, but seat might be different i believe the 01-03 F4i's had the split seat (two physically different seats, one for driver, one for passenger), and the 04 and above had the split level seats, or banana seats. Shared a cushion with driver, and passenger.
