Three wires out of the points, but two on diagram?

Not sure if anyone can help but I am rebuilding a 78KZ650 B and I see on the diagram that there is a green and a black wire coming out of the ignition points. This bike came in a bucket mostly so I have been doing a LOT of (mostly successful) guesswork.

Out of MY points (which certainly appear to be original. The bike only had 13K miles on it and it had been stored for 25 years or so.

Green
Black
AND a blue with red stripe. I am curious about why the diagram and the actual parts don't match up. Feels like the blue/red wire needs to go somewhere but I do not see it on the diagram and it is the correct diagram for a 650B.r

Aha! It is the oil pressure switch. Got it! Thanks all.

Ya beat me to it. :laugh: Here's a wiring diagram for future reference. Ed
