Just put in a Y8 harness to finish my Y8 conversion. I didn't plan on the harness have a 2 wire O2 sensor for the secondary O2. Wich wires are the ones that need hooked up. I guess I'll just take the 4 pin connectore off the old harness and leave 2 pins empty. This is on a 96 Y8 harness.

 

ok maybe I've got something mixed up. What I thought was the secondary o2 sensor maybe it's not. It's a connector that looks just like the one going to the Idle Speed Control and is Y'd off the wiring harness under the intake manifold. I don't see any other connectors that could be for an oxygen sensor. The 96-98 does use a 4 wire secondary according to the manual.

 

yes i was going to say after reading your first post that you shouldnt need to convert anything...

 

that's not good I don't see anything that could be the secondary o2. I see in the parts list that there should be an extension wire between the o2 and the wiring harness is that correct?

 

ok the one I thought was an o2 has a black and green wire. Any idea what that is supposed to goto?

 

im not too sure on the fine details with the eks but im pretty sure that unless its a cx or an hx then all the o2 sensors are 4 wire.

 

old wiring was a CX which was 4 wire. okay I'm going out to start looking it over again.

 

I belive its by the cat next to the shift linkage.

 

ok looks like the connector I thought must be it is to the PS rack pressure sensor, which of course I don't have. So I still need to find the O2 wiring. I'll tear it apart tomorrow I guess.
