EVO8 Marelli dashboard

Hello,

I willreplace the original dashboard unit of my EVO7 by an open Marelli MDU LCD.

To displayengine-rpm, vehicle-speed, water-temperature, fuel-level and ACD-status I wantto use the signals which are on the original dashboard connector.

For alladditional information like boost-pressure or oil-temperature I will use my ownsensors.

Can anybodyhelp me with the pinout of the original connector, and even more important withthe signal characteristic of the mentioned channels?

In detail Ineed the following information to setup the input channels of the Marellidashboard:

- rpmsignal (I assume a digital signal 0-5V, n puls per engine revolution)

- speedsignal (similar to rpm)

- watertemperature (I assume nonlinear characteristic of the NTC thermistor or linearanalog signal output of the ECU)

- fuellevel (I assume an analog voltage or resistance value of the fuel level sensor)

- ACD-status(analog signal with three-step threshold or three digital signals?)

thanks in advance

If you can't read a wiring diagram to figure out those inputs and what connectors they come from I have absolutely no idea how you plan on accomplishing this entirely-electrical project on your own...
