You need:
Solder gun, solder, Heat gun (hair dryer could work), shrink tubing, ground wire connectors, extra 12g wire for all the ground wires you put together, Klein tool crimper (dont skimp here, these make all the diff in world for crimping)
Klein Tools Crimping/Cutting Tool Non-Insulated/Insulated - 1005 at The Home Depot
I used some electrical tape in spots, I also used a magnafine glass to see them little tiny #'s on the stock connector ends. I think I covered it all.
I did remove the battery covers and tank (I put die electric grease in all my fitting under the tank and shrink tubed them). Hind sight, I would have taken the whole harness out and wired it outside the bike. And I'd of bought the 3 pin connector from Jake and put that in between the coil and battery.
Hope that helps.
