Putting an aem wideband on my all motor b series build. The o2 sensor plugs into the wiring that goes to the gauge. What do I plug into the plug for the stock o2 sensor?

 

You don't.

 

The stock o2 sensor?

 

^Oh yeah. What he said.

 

I only have a place for 1 sensor

 

You. Weld. In. A. Bung. For. The. Wideband.
How did you not plan for this before you bought it?

 

I thought it would plug into the stock spot but I was wrong

 

Or u can chip the ecu and disable the o2 sensor

 

Factory o2 is for ecu to spread and adjust fuel.
Aem wideband is for montior what's going on. You need to add another bung for the aem sensor.

Also aem ugeo has a output wire for datalogging. Which can be use in many ways.
