Need help finding the 02 sensor wire...
When I picked up this 83 500SEC the exhaust had fallen off the car so I have been searching for the 02 sensor wire to hook up for the new exhaust. I found a single, curled up white wire that goes through the tunnel that is not connected to anything so I am going to hope that is it.
Can anyone confirm this is the 02 wire?

Hi
It is either a 2 or 3 wire set up. Ther 3 wire is for the heat to the o2 sensor.
Are you sure you had one on it?
My 84 500SEC does not use one no cats were on it when I got it from the original owner.

Hmmmm well parts websites list a single wire 02 for these cars but since I cannot find wiring diagrams or anything I was just under the assumption these cars have 02s.
But seems the word is no 02, so that works too. Thanks!
