I followed the how to on connecting a wideband to the rear O2 for ECU logging. He uses a yellow wire from the harness to connect to the ECU. My harness doesn't have a yellow wire, apparently they are not all the same. The sensor has been removed, and disabled in the ECU. I know I'm in the right spot because I removed the sensor myself and un-clipped the connection. My car is a 2012 MR. Does anyone know what color wire I need to use by chance?

 

I've been searching quite a bit and came across some other posts showing that the yellow wire change to green sometime in 2012 I believe. There are other posts confirming 2013's are green on another forum.

 

Awesome. That helps a lot. Thank you sir.

 

no problem
