My coils are from GSXR600, the harness connectors are from a CBR. Different years GSXR600 had different coils. You can see that going thru the eBay listings. I have a second set of identical coils comming, only $20 and will be good to have extras onhand. The connectors are expensive and hard to find new. The best way is to harvest them from an old harness, as I did with the CBR. On eBay there are quite a few listings for coils and harness together. That would be the best way to go.
Went on a ~150 mile ride over the local mountain today with my little one. Ran great.
