Muzzys 86-09 Ford Mustang 24" O2 Oxygen Sensor Extension Wire Harness Sold individually. Order any quantity you need. Made in the USA by Muzzys! Intended to extend the upstream O2 sensors; however, can be used upstream or downstream if needed. The additional 24" length these harnesses provide allow the O2 sensors to simply plug back in from the new location, designed with OEM harness connectors for simple installation. The connectors may require the small directional tabs to be removed on the ends of the connectors to fit some applications. Can easily be clipped or filed off. Will fit ANY 1987-2009 Mustang, Cobra or Shelby. The connectors are all nearly the same.
