Mazda CX-7 Pinout / Diagram Urgently Needed!

[AlvinDj]

Any kind bros out there who is willing to share with me the ECU Pinout / Diagram of CX-7?

I am trying to look for the RPM Signal on the ECU for my newly purchased Tachometer gauge but I can't seem to find any ECU Diagram or Pinout at all! (boom02)

Any help would be very very much appreciated..!!!
