Oxygen Sensor - Question - Ingo?
 

When I swap back to my original exhaust from time to time I want my Oxygen Sensor connected...but the wrench who did the initial install of the new muffler cut the wires to the Oxygen Sensor.

I notice there are two white wires, are they the same or how do I tell them apart?

Damn this should be so simple yet I feel so stupid. :confused:

It doesn't matter since it's for the heating element.

Cheers,

Joe

Joe is correct. Here's a bit more detail: http://forums.pelicanparts.com/porsche-911-technical-forum/230733-o2-sensor-polarity.html?highlight=bosch
