# HOWTO M73 V12 on Proteus
|
|
|
|
* [rusEFI Proteus](https://www.shop.rusefi.com/shop/p/spring-blade-cyy7n) can run M70/M73 port injected v12
|
|
* we do not support unusual M73 throttle bodies, we also only support 6 wire pedal position sensors. Nissan throttle bodies are the best fit we found for M73
|
|
* MAP sensor fuel control strategy is recommended that would require MAP sensor to be fitted on the engine
|

See also [Vault-Of-Electronic-Throttle-Bodies-ETB](Vault-Of-Electronic-Throttle-Bodies-ETB) Nissan Hitachi SERA576-01 60mm throttle body recommended. In order to mount SERA576-01 you just need to drill ETB bolt passages to 10mm / 3/8".

|
|
~6 wires are different between [Proteus 0.2](Hardware-Proteus-Wiring-v02) and [Proteus 0.3+](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
|
|
|
|
Total wires between Proteus and GREY - 10
|
|
Total wires between Proteus and BLACK - 22
