Ok, here is what I have, need to know which wires to put together. I got a diagram of the O2 sensor and the wire harness but still need to know what goes with what. Harness.... Black w/ blue stipe = sensor ground Tan w/white stripe = upstream heated sensor signal Orange w/green stripe = automatic shutdown relay output Black = ground O2 sensor..... White = 12 volts DC heater positive White = heater ground may be switched by ECM or Relay Black = Sensor signal reference Gray = Signal Ground (permanent) Usually goes back to ECM Manufacturer says white wires are interchangable since there is no set polarity to either wire. Could anyone PLEASE tell me which wires to hook togerther.
Hard Wiring an upstream O2 sensor on 1998 Dodge Durango

Here is my suggestion for your 1998 Dodge Durango: Orange w/green stripe = automatic shutdown relay output, connect to: White = 12 volts DC heater positive. Black = ground, connect to: White = heater ground may be switched by ECM or Relay. Tan w/white stripe = upstream heated sensor signal, connect to: Black = Sensor signal reference. Black w/ blue srtipe = sensor ground, connect to: Gray = Signal Ground (permanent) Usually goes back to ECM.

Are you installing an aftermarket sensor, is that why the wires are different? If so, you're asking for trouble, these sensors are made to work with a specific system and using a generic sensor may cause the light to come back on again. I would tend to agree about the white wires, they are feeding power to a resistor, and they should attach to the Orange w/green and Black harness wires. The Black sensor wire = Tan w/white stripe and Gray = Black w/ blue stripe. Those are my guesses, but I would be using a wiring diagram, checking the signals to the sensor from the ECM and checking the sensor with a volt/ohm meter just to be sure I was 100% sure. Good Luck
