Hello I would like to know what is the pin from maf connector 0-5v.
The wiring schematic didn't specify which pin is.
Also the signal pin use car general ground or use ecu reference ground?

 

The wiring diagram should have indicated the wire color(s), right?

 

Yes i have the color of wires but wich one is the signal

He already has the wiring diagram, but it doesn’t indicate which is which as I was expecting.

My apology for that misunderstanding. Based in the 2005 Service Manual information it appears to be Pin C (5N) in the middle, ground is indicated as Pin E (4U):
