Where is the easiest/best place to tap into the oxygen sensor line?

Other than at the ECU that is.

Thanks,

 

I'm now waiting for the torrent of "narrowband gauges don't work" posts.

That said, you can tap into the wire coming off the sensor itself for ease of getting to, but your connection should be REALLY sturdy as it's by the hottest part of the engine bay. Best place is the ECU wiring, as far as being clean.

thanks,

the ECU it is then. I don't think my connections wouldl hold up to the heat.

 

I'll say it: narrowband gauges don't necessarily suck, but the stock O2 sensor isn't accurate enough to measure the AFRs that you should be concerned about. If it was, you wouldn't hear about people grenading engines on stock ECUs.
