Default 4EAT to STi gas pedal wiring guide

One of the last bits for my STi swap was the gas pedal. I swapped the gas pedal because it's hard to heal-toe as the 4EAT gas pedal is way below the MT brake/clutch, and to have the gas pedal not level is a hazard IMHO (my foot got stuck under the brake pedal, not fun ). Also, I noticed the travel is a bit longer in the STi pedal.

06 STi Acceleration Pedal 6 Pin - STi acceleration pedal pinout colors are the same from 04~07. As for functions for the target car... look at your ECU pinout for your year.

Terminal - Color - Where it goes - Function
  • 1 - Sb - ECU Port 136 Pin 16 - Fuel Tank Pressure Sensor - Sub power supply
  • 2 - L - ECU Port 136 Pin 28 - Sub sensor signal
  • 3 - Lg - ECU Port 136 Pin 15 - Main Power Supply
  • 4 - Y - ECU Port 136 Pin 34 - GROUND (main sensor)
  • 5 - R - ECU Port 136 Pin 17 - Main censor signal
  • 6 - RB - ECU Port 136 Pin 35 - GROUND (sub sensor)


06 WRX Acceleration Pedal 6 Pin (MT/4EAT) -

Terminal - Color - Where it goes - Function
  • 1 - RL - ECU Port 135 Pin 22 & Fuel Tank Pressure Sensor - Sub power supply
  • 2 - RG - ECU Port 135 Pin 30 - GROUND (sub sensor)
  • 3 - L - ECU Port 135 Pin 31 - Sub censor signal
  • 4 - Lg - ECU Port 135 Pin 21 - Main Power Supply
  • 5 - Y - ECU Port 135 Pin 29 - GROUND (main sensor)
  • 6 - R - ECU Port 135 Pin 23 - Main censor signal


So using the information above:

06 WRX - 06 STi
1 - 1
2 - 6
3 - 2
4 - 3
5 - 4
6 - 5

If you're doing a 4EAT to MT swap, I would recommend getting the gas pedal as well.
