hell, wiring is different between 86 and 87.
so the handlebar controllers may not work... correctly.
the TCI (ig box) has a different connector.
you need a new TCI so it may be an option but if you do you'll need to swap the rotor for a newer one.
The signal light connectors maybe different, not sure.
so if you're going to use the 03 harness, you may want to replace everything.
At this point I already have to replace the whole electrical system, except for the reg/rec. I'm also planning to add new lights, signals and handlebar controls. My other option is to use Clymer's to solder one together, but I would still need new connectors.
Also, thanks for that cam chain tensioner!
