This is what I have documented for the 16 pin connector on Japanese market cluster:

1. Light Blue - Alternator Charge Warning
2. Violet - Brake fluid level warning
3. No connection
4. Black - CEL
5. White - Auto Headlight Warning
6. Sky Blue - Front Fog
7. Red - Rear Fog
8. Light Green - Left Turn Signal
9. Orange or Beige - Passenger seat belt warning
10. No Connection
11. Pink - Illumination
12. Yellow - Oil Pressure Warning
13. No Connection
14. Green - Hi Beam Indicator
15. Brown - Right Turn Signal
16. Green - Headlight Indictor

This is same as the chart you sent me a while back, unfortunately for JDM meters its not right. The JDM meter has almost sort of reversed wiring pattern to USDM and EUDM.

Thats why I asked for the colors, with that I can make a wiring chart for JDM meters. I have a couple of queries though:

the orange wire, why does it go to the cluster? the passenger seat belt warning is shown on one of the panels next to the ac vent.

some of the colors dont match up with what I get. e.g. the red, pink, light green.

I wonder why Toyota didnt keep their wiring pinouts consistent over regions.

That chart is actually directly out of the JDM Vitz wiring diagrams. It looks like your car (which would be considered Asian market, rather than JDM) has different wiring from JDM.

I would inquire with your local Toyota dealer to see if they can print you a copy of the cluster wiring diagram.
