I'm attempting to rig up the O2 on my 88GL, and it appears that the correct wire is shielded. I don't remember ever seeing anything except single wire 02's on these cars.

Incase your wondering, the original 02 connector was still hooked up when I dropped the exhaust, and it ripped out of that section or the wiring harness. I did not get a good look at the wiring at that time, and the 02/connector setup is long gone. However, as I said, the shielded wire seems to be the right one for the 02.

 

thanks, John

Yep.. The body side of the wiring to the O2 sensor is shielded from it's connector to ECU connector. You should be able to splice new connector onto the body side with no problem, other than making sure you do not have any of the shield wire mixed in with the signal wire.

 

Note: Just so you know..

 

There are a few "shielded wire" circuits in the harness for any ECU system on these Subarus. All of the shields are centrally grounded within the wiring loom. Therefore, even if you have all of the connectors of the loom unplugged, you will still read continuity to ground on the shield wire of any such circuit.

Hey Tom:

Thanks for the clarification.

I knew there was some sheilded wire circuits, but did not know that the 02 was one of them. None of the schematics I looked at indicated sheilding. Makes sense though, since other sensing devices are sheilded.

Appreciate your response. Always learn something new...
