i need to know which pin on the ECU is the Signal Wire for the Oxygen Sensor? ive tried the ECU diagrams for 02 and 04 Sti. No Luck the Pinouts and Harnesses are completely diffrent.
i tried a few wires and the gauge LED's flicker. but still no luck on finding the right wire.
ive searched and came up with nothing i would like to have this done today.
i have a 05 WRX sedan.
