I was just curious if the o2 sensor's are interchangeable on a 2g? I know the connectors are different so a bit of soldering would be necessary. Reason i'm asking is I recently installed my 3" exhaust and i'm not using the rear sensor anymore. My front o2 has crapped out on me, so I was thinking of trying the old rear one in the meantime. I'd like to eventually get a wideband, but of course would have to mount it in the downpipe. Anyone ever re-wire a rear o2 in a 2g?
