Has anyone out there done their own Air Fuel gauge install. I bought Autometer A/F and boost guages and I want to install the A/F guage before I order my Vortech kit.
I need to know which wire you used for the 12V power source and for the 12v dash light source. Also, which is the O2 signal wire coming from the heated O2 sensor.

Thanks!

 

Unless the Autometer recently launched a wideband sensor, then those narrow-band gauges are absolutely worthless from a tuning perspective.

If you are running F/I, true wideband is the only way to go. Various companies make them for $300-$500. I am familiar with the AEM wideband UEGO, but I bet others on here have experience with some of the other models.

Hope that helps.
