Toyota liteace 4x4 tdi 1990 Gauge wiring finding /needs

[Mattzilla]

Hi, it's been a while from my last post (3 years), but finally I find a excellent and honest mechanic who can end my liteace 4x4 2.0 tdi cm40.
In this time a make A LOT to the van, but I will make another thread because it's REALLY a lot :')

In this time I need your help, I'm searching the wiring diagram of the gauge. This liteace have a mess with the wirings and are like all the same color 🫠. So if someone have the diagram I will be REALLY grateful you can share with me please.

I leave a few photos of the gauge and the van.

Thanks to all and greetings
