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.
