The white connector is the coils and points. Black and green are points and it should have the yellow red for coils.

edit. The white connector might be the brake light failure switch. What are the colors

Thanks Mikaw, you're a Godsend.  This helps tremendously.  I wonder if this harness is used on the Cop bike?  Could the white possibly be Cop bike related?

On my KZ900 the brown and blue goes to the horn.  I'm wondering if the front brake line is run through the plug coming off the right handlebar control?

Horn is brown and black. The black comes off the LH control separate, not in the connector. Brown is 12volt

Points connect to the coils thru a two wire harness from the points. Black and green. They connect direct to the coils.

I'll tell you, it's like someone set a monkey loose with a soldering iron and a wire cutter on this electrical system.  He's got splices and goofy connectors all over the place.  He had removed the panel under the right side cover and had this crap connected to a couple of these square connectors.  Then he replaced the rectifier with a solid state regulator rectifier and cut into the harness and spliced the leads. When I converted my first KZ to regulator/rectifier it came with a canon connector that just plugged into the panel.  Also, can anyone identify this regulator rectifier?

The three wire connector near the coils is part of the brake light warning system that appeared in 1974, warning light in tachometer, 28019-001

That is .in fact yellow red with double fem connector.  Making more sense little by little.  What goes to the blacks coming off the coils?

There's no name on it, just some numbers on the back that I can't make out.

The points plate has a long green wire and black wire that goes under engine then up to coils.
A yellow/red wire supplies +12 volts to the coils.
