Wiring ID issues.

Hey guys,

I need help identifying the wired that come out of the engine by the 2 yellow ac generator wires and the big black starter motor wire. It looks like they're green/red, blue/red, and then maybe solid blue in a little larger one. I think they're neutral switch and oil pressure switch.

The second wire is down by the ignition. It comes off a sensor. I also thought this was oil pressure...

It would help to know just what bike you are talking about. Your user name indicates a 78 kz650, but which model?
