My A/F gauge
Alright guys, I know this has been anwered for me before, but I am horrible at the whole searching thing. What wire/ pin on the ECU (88 TII) do I need to use when hooking up the AF gauge. the plug in the engine bay isnt cutting it. Thanks

if you tap into the o2 sensor itself directly will you get an accuate reading?
well.. autometer af isn't exactly known for accuracy but ya know.
will the tap affect the voltage signal from the o2 giving your ecu tainted information?

I tape in the O2 sensor wire....
the only differnce is it will read lean on start up not rich.....though a/f meters are not needed as much as other gauges are..........

yes yes EGT I know 
That'll most likely be a 3 gauge purchase.. EGT, coolant Temp, and Oil pressure.. but for now I seem to have a hole in my wallet
thanks for the advice

IMO, I wouldn't tap Into the O2 Sensor being Copper Sheild In all. I woulldn't want to disrupt that. I plan on Installing my A/F Ratio Gauge soon.
Can anyone confirm If the Diagram, In the Thread, Is accurate In terms of Installing the A/F wire at the suggested pin?

Any A/F gauge wired to a stock sensor is vague in it's readings to say the least. Taking the signal right from the O2 sensor wire is fine, just keep in mind how inacurate the reading will be. From what I've seen of the Autometer compared with a true wideband the Autometer should read full rich on boost.
