I'd splice it into the existing harness. The only thing an "after cat" O2 sensor will do is verify the function of the converter. If you're using the O2 sensor to adjust your air / fuel ratio, it needs to go in FRONT of the cat.is it ok to splice into a exsisting one for the computer or would you suggest a seprate o2 sensor. does before or after the cat make a diff?
thanks

With what? The question referred to the placement of the O2 sensor.i disagree.
I tuned mine quite successfully with a narrow band sensor. When I went to the wide band, a little bit of tweaking here and there was all that was necessary. Tuning wasn't very difficult at all, especially when I had computerized tools to help me develop a good fuel map. Megalog Viewer has the capacity to create customized fuel maps based on data developed from actual driving--it's a poor man's dyno, and it worked really well.i would either fork over the cash for a wide-band O2, or not bother with an A/F ratio gauge at all. the factory sensor spends its time cycling from rich to lean, the computer averages the signal to control the long term fuel trim. your gauge wont average the numbers so its just going to reflect the rich-lean-rich-lean cycling of the narrow band O2 sensor every few seconds. its not going to be very especially if your trying to tune the engine after a major power increase.
