Oxygen Sensor - Question - Ingo?

[k9handler]

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.

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

Cheers,

Joe

Joe is correct. Here's a bit more detail: O2 sensor polarity?
