Hi i have a 2007/2008 subaru wrx with a AZ1E400C pcm. But have noticed these 2 plugs under the lh foot well that piggy back to the ecu im Thinking they are for live tuning but not 100% shore. The vehicle has been previously tuned. Is there any way to tell what these 2 plugs are for or what i should be looking for in the ecu to see if it has been modified?

They do not look like any connector for tuning that I have seen used. You would need to trace them back to the pins on the ECU to see what they are connected to.

They may have been installed as part of a bypass for an alarm even.
