Rear 02 Sensor
I'm in need of a 4 wire rear 02 sensor , the one after the cats. It has a tan connector with a yellow nitril seal. Part number on the connector is 002 540 31 81. I will also except a bad one . You might need a Magnifing glass to read the part numbers. Attached pictures will show you where the numbers are located . I just need 1 more connector to complete the project. Thanks _PTE_
