Hi and thanks for this resource.
I'm putting my 1983 KZ750L3 back on the road ...had the battery box repainted and now connecting the wiring bits back in place.
I am the first to admit I am terrible at reading a wiring schematic.
Asking for help: in the following link/pics there are a few leads which seem to not have mates. Any suggestions from the good people here as to what I am missing?
The red and white ones on the clutch side of the battery box ...

then the yellow/black and white/blue near the battery box itself.

Suggestions welcome. Thanks in advance for any thoughts.

Looks like you are missing the round hazard flasher. Orange/green wires (2 of them)

The White/red most likely goes to your R/R.

Yellow/black is a ground. Not sure to what...

The white/blue is an auxiliary power feed line. I don't think you need to connect it unless you are using the connection upstream.

Thank you.

I'll go searching for one on eBay.

You can use a turn signal flasher from the auto parts store. An electronic heavy duty trailer flasher would be good.
If the voltage regulator is missing, you should be able to use one from a Ninja 500 or Vulcan 500 to around at least 2009.
I installed a reg-rec from a low mileage 2007 EX500. (alt r/r credit to loudhvx)

The pdf manual link is near the bottom of the list. good pdf scans.

Wiring diagrams. mbsween. bike-night. KZ750L3 . Scroll down & click "The Bible" link.
the site has wiring diagrams & a manual that isn't scanned as good as the one on the Turbo site.
Note: some of the wiring diagrams are mislabeled in the links: the 1981 Ltd is an H2, the 82 is an H3, & the 83 is an H4.
