M73 wiring diagram

~6 wires are different between Proteus 0.2 and Proteus 0.3 - all on the 23 pin plug.

This HOWTO is focusing on M73 engine with stock ECU harness. 1998 stock ECU harness has two 134 pin connectors.

On my 1998 first set of 9+24+52+40+9=134 pins total is BLACK.

Second set of 9+24+52+40+9=134 pins total is GREY.

rusEFI uses six wire colors: black white red orange green blue.

Proteus

  • +12 from main relay
  • x12 injectors
  • CLT
  • IAT

Total wires between Proteus and GREY - 10 Total wires between Proteus and BLACK - 22

Destination legend: "Black #3 40/52" means "Black set of ECU plugs, connector #3 - pin 40 of 52 total pins"

Pictured Proteus with ampseal connectors, non-BMW pedal sensor, two non-BMW ETB connectors, igniter, two breakout boards for the stock connectors.

OEM pedal and ETBs are too unusual thus complete redesign of pedal and ETB hardware and wiring.
