get the pdf for your model, it has all the pinouts listed.

also, when hooking up and setting up your wideband in the aem software, unplug the 02 sensor and the wideband will output 2.5V = 14.7 afr. then you have to use the aem software to scale the input so it matches, meaning 2.5v on the wideband = 2.5v on the aem software display. once the scale is set, you can plug it back in and it should read properly. we had this issue with my car.
