WIDEBAND AFR Gauge INSTALL || HOW TO || Hemi AFR GAUGE Wire Up Install/Location with Headers + RUNS

In this video I cover how to wire up any gauge to the cigarette lighter location behind the dash. This type of install ensures the gauge can not draw power without the vehicle being on.
The gauge/wideband used in this video: AEM X Series 30-0334 with OBDII interface. This type of wideband is most commonly used for tuning, more specifically, wide open throttle tuning. Car featured in this video is a 6.4 HEMI, bagged, e85, and headers.

@lavongreen6908 oh yes!! The best on the market I love em

[@austinkeeton3497]

I have the aem 30-0300. Has red, black, blue, white, brown, green/black, etc. I was told I only need to use the red, black, and blue, where could I ground the blue wire to?

[@austinkeeton3497]

Also have a prolink cable with my hptuners

[@ReidPerformance]

I’m not sure what the blue wire is for. I only used the red and black wires.. and just connected them both to the cig lighter harness

Where on the exhaust did you put the new bung on? I'm going to install my sometime later this week. Great video.

[@ReidPerformance]

@joellopez6913 thank you! I put it in the midpipe.. about 10 inches or so past the upstream O2 sensor

[@joellopez6913]

Sweet thanks

[@ReidPerformance]

@joellopez6913 happy I could help

Wait ! If you swap the OEM O2 sensor with AEM O2 sensor on the exhaust manifold, how will the ECU get the oxygen info ? Ideally, dont you want both sensors to be installed ? One for the wideband and one for the ECU ? Please clarify.

[@ReidPerformance]

@soufianDEMOS you are correct.. you need both O2 sensors. You must get a new bung installed by your local exhaust shop prior to… you DO NOT want to ever run without the oem sensors installed
