Not really possible. The computer will not be able to decipher the information from the wideband, it's not programmed for it.

Actually very possible. A UEGO wideband can send out the signal
& data to the ecu that it needs & also send info to a logging device. There are made to replace factory o2 sensors. Just looking for some wiring help.

I need the wiring diagram for the upstream (closest to engine) factory o2 sensors on a 2014 GMC Sierra 1500 5.3L

Hello and welcome to JustAnswer!

The violet/blue wire is the power feed for the heaters.

On the 1/1 sensor the gray/white is the heater driver.

White/black is sensor ground.

Violet/gray is signal.

On the 2/1 sensor green/yellow is the heater driver.

Violet/white is signal.

Yellow/white is sensor ground.

I hope that helps! My goal is your satisfaction today. If you feel I've been professional and helpful, your 5-star rating at this time is most appreciated. However, if you still need my help you can reply back here and I'll respond as soon as possible! Thank you!
