[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)


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.
