Where to get O2 sensor wire
"After" would be the engine harness side and repairing will be a quick solder job.
If you damaged the wire directly connected to the 02 sensor I would recommend replacing the whole sensor and it will come with a new wire/connector..
02 sensor wires are not regular wires like the rest of the car, they are designed to heat up the sensor and are not recommended being repaired like traditional wiring.
