[M73 wiring diagram](BMW-e38-750)

~6 wires are different between [Proteus 0.2](https://github.com/rusefi/rusefi/wiki/Hardware_Proteus_Wiring_v02) and [Proteus 0.3](https://github.com/rusefi/rusefi/wiki/Hardware_Proteus_Wiring_v03) - 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


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