best guess...the yellow is power for lights.yellow/red is pulse, green-not sure, ground probably, black is to kill switch. red is ignition voltage. Grounding the black wire should kill the motor. the C model had e-start, the B model did not. So the C model would have an extra wire to charge the battery. May have to remove the flywheel to see what wires go where, but based on my experience with the older Yamaha motors, this should get you in the right direction.On the key switch... extra blue/bl-w are for e-start probably.
Don't forget your dealing with point and condenser here...
Let me know how you come out on this

well got to reasearching and multimeatering well the switch and kill switch that are stock off the sled are getting removed .. going old school on it older ground type switch and cat teather are going to work with a toggle for lights since it doesnt have break lights just a light for a tail light .. should work great will find out tonight ..

I got it --all good now !! black to key to kill to ground red tach green to lights all working great !! now running and able to move on its own and shut off properly and have lights .. now just need to figure out the secondary clutching make it whine out more used a 340 enticer drive set up in sled running a 292 eng clutch opens up to fast so eng wont whine out..

I actually saw someone parked at boot lake with a 292. That had to be a ROUGH ride!
