FD gauge dash: how the hell this thing works?

[mazpower]

Oil pressure, coolant temp, and fuel level are all sending unit driven gauges. The speedometer, tach, oil level light, coolant level light, and all other lights are driven by the ECU INSIDE the gauge cluster.

There´s an ecu inside the gauge cluster? Besides the load ecu and the main ecu¿?

from the schematics my conclusion was:

Oil pressure, coolant temp, and fuel level = analog signals, easy to do

Tach = signal from coil

Speedometer = signal from gearbox, goes to the ecu and then to the dash

Pics... easy to read schematics or idiot notes would be great

I need a "GAUGE CLUSTER FOR DUMMIES" kinda thing,...
