Oxygen Sensor Harness Question
 

Ok so recently my downstream O2 sensor shorted out and melted its own wiring harness and the other side. The harness plug that connects to the car.

Well I just purchased the O2 sensor but I need the other side and I can't find out what its called.

Does anyone know what it is called and where I can buy them?

EDIT*

It is a 2000 Hyundai Elantra, sorry
