hey guys i have a car that a h22 swap had been done by the previous owner and same with the gauge. the wiring was tied into the aftermarket audio harness(power, ground, output wires) I didnt notice it till i had the whole harness pulled out bc im replacing the headunit and ive never installed a wideband before. is this standard way to install these wires from the gauge? if so what do i tie the two output wires into? and if not what is the usual way? any help would be awesome and yes i did try to search here and online and im still lost.

 

You say you tried searching...but did you actually try? Because "AEM wideband wiring" on Google gives you this. You don't even need to scroll.



Assuming you aren't running any kind of datalogging, red goes to power, black goes to ground, and white and blue just get capped. If you are running external datalogging, you run white for a voltage output, using black as a unified ground, or you use blue as a serial (raw data) output.
