Am working on a Yamaha XS650 1979 and I need help to figure out the electric part missing in the wire harness, am attaching pictures, hope someone can help

That looks like the connector that goes to the light box between the speedometer and tachometer.

In the headlight, looks like the middle plug in the harness diagram. Can't quite make out the red/black wire in your pic tho.

Yes, light box. I believe it's also called a pilot box.
