What’s up every one?
The wires that connect to my O2 sensor from the wiring harness melted on the exhaust. I found out because the check engine light came on and the O2 sensor code came up. I do not want to replace the whole harness, too expensive. There is a connector by the firewall for this part of the harness. Just need to find it, anyone know?

I would just splice in and replace the melted section for the least cost if it's on the vehicle side of the harness.
