Need help finding rear O2 sensor harness

[Ichito240]

I had an S14 SR swap and I am now back to a stock 1998 KA engine and need to pass smog but cant seem to find the harness to connect the rear O2 sensor. My car is 1998 and if you can give me any suggestions as to where the shop might have put the harness or how I can find it that would be great. The shop that did the swap was R & D factory if that helps.

Thanks

Any suggestions at all guys. I have heard under carpet of rear, center console....Car is a 98 and I just don't wan to dismantle my interior if someone can let me know where to find the wire to hook up the rear o2 sendor.

last i remember, i believe the rear o2 sensor harness is on the lower transmission harness...

Thanks alot Dalaz, it was on the lower transmssion harness like you said. Now I need the connector end that plugs into the rear o2 sensor, the wires were cut so I'm missing the connection that hooks up to the rear o2 sensor connection. Anyone know where I can find one??

its the same as the upper o2 connection if it helps...find an obdII enging harness...actually...i might actually have a hacked up OBDII engine harness laying around...

[Ichito240]

Let me know if you do, I would like to buy that off you if you find it.

im 95% positive, its in my box-o-shit...i also have a spare OBDII o2 sensor of a 98 KA...

check to see how many wires are on the harness for it...

[Ichito240]

I think thats the wrong one, I need one with the 4 wires and seems like the connections are larger on the one that I need.
