I read a post somewhere askingfor the wires to hook up a A/F meter to the stock O2. I hooked up one on my car before I got a aftermarket o2 for it. It is a 01' with the AWM head and it has a wideband stock on it. This is how I did it on the stock ecu. There is two pluges into the ecu. The wireing harness on the ecu thatis closes tothe drivers side fender towardyou, you need to find one of the these wires: a yellow w/ grey stripe and a yellow w/ red stripe. I t-tappedone of them and got a signal from either one into my profec e-01. Here is the alldata schematic on it:



I don't know if this is the same on any of the other years or heads. Enjoy if it is the same. I hope no one else has posted this same thread......
