i got an Air/Fuel gague and wondering how I hook it up. I think that the purple wire off the gauge hooks up to the purple wire of the o2 after the connector. where exactly is the connector located? pics would help alot

i know your out there

You need to tap the purple wire. The connector should be clipped to the rear fuel rail. Just follow the harness up from the O2 sensor. Allmachtige works for Autometer, and has an A/F ratio gauge installed. He can be a bit better here than me.

Do you know where your o2 is? It looks like a spark plug in your exhaust manifold behind the engine, by the firewall. You most likely (>99.99%) have a 3 wire, so make sure you got 3 wires at some point there as well.

yea i know where the O2 is and yes it is heated (3 wires)

I am trying to find what number on the PCM connector is the o2 is so I dont have to run a wire through the firewall

any one know
