'''Disclaimer & warning:''' 

Be careful when using these diagrams. The harness changed bit by bit over the years. You can use the schematic to find the wire you're looking for, but don't assume that it's correct. Test any wire for function before splicing into/diverting/eliminating it. For instance, the wiring diagram in the 2002 Service Manual Supplement isn't even 100% correct for the '02 bike, and the '04 is different yet. 

'''Tip''': Yellow and black wire is ground throughout the bike.

====Assorted schematics by Anna's Dad====

[http://www.ninja250.org/Anna%20Dad Anna's Dad] is pretty good with CAD software, and he has drawn up a number of useful diagrams and schematics for the 250F. The full-color ones listed above are his. 

He has set up a site where he can post his drawings and any updates he makes to them. Follow the link below to the table of contents:
