o2 sensor in collector or runners?

[Bigsyke]

I have the option to put my o2 sensor in the runner of cylider 2, or the collector. Ive heard to pros/cons of both, however the KA24de o2 is a non-heated 1 wire, thus it needs to be warmed up, but I would still like it to have a acurate reading of all the cylinders, thus the collector.


Anything wrong with extending the harness and plugging it in the collector?
