SubarU STI N12 Wideband wiring

[bjorgvinben]

Hi,
I am working on wiring wideband sensor to M800 plug-in on Subaru STI N12
I am wondering if the the original wiring loom and connector are wired to the ECU Wideband controller and can therefore be used.
I have not yet traced the wiring yet.
regards
Björgvin

The WRX9-10 board has a separate connector with loom on the PCB that should correspond w/Lambda 2. If you are using the on-board knock module (OKM), Lambda 1 will be utilized for knock control.
