I am currently trying to find pins and seals for the stock R6 coils. having had horrendous problems with wirng previously I am trying to wire up the car without any bodges within the wiring (especially the with the coils).
The only information that I have found so far is that they might be a sumatomo connector.
Does anyone know where I can get these pins?

You should be able to get connnector kits from your yamaha parts dealers

We used pins we had that fit on, but having no plugs, we glued them in and created a "flying loom"

This is pretty easy if you can't find the right plugs.
