Anyone install an A/F gauge yet? Which wire did you tap into for the O2 sensor? Assuming you got an a/f gauge that taps an existing o2 and doesn't come with its own. Thanks!

You don't - you get a wideband o2 sensor and a bung welded in the exhaust. Stock o2 is slow responding and not really useful from what I gather in about 2000 other posts.

Matt is right. The single channel a/f gauges are worthless. If you want to monitor your air fuels, then you need to get a wideband 02. There are several different brands availible or I have a USED AEM unit if your interested.

if you doing the a/f gauge for show just find the tap wire for signal in the o2 sensor. There should be 3 wires. white black green. on my last car it was the green wire. Not too sure for the TC, just letting you know ahead of time, but the white should be power and black ground.. so green is the only thing to shoot signals
