I have a 1996 Dodge Neon 2.0 L Vin C. DTC P0171 when I went to change 02 Sensor. I saw that my upstream 02 sensor connector harness side got melted, was to close the the exhaust. Don't know how to find which wire goes where, how do I figure this out. Your help will be so much appreciated. I have a wire diagram, still need help please.
