This auction is for a 4-wire O2 sensor wiring harness and plug that came off of a 1999 Acura Integra LS. This part is in good working condition. It should fit all 98-01 Integras and probably all obd2 Integras that use a 4 wire O2 sensor. This harness is probably compatible with other Hondas and Acuras that use a 4 wire O2 sensor.
