O2 MIL Cheater for '00-04 Focus

This part attaches to the 2nd 02 sensor on any Ford vehicle. This harness is used to eliminate a check engine light in cars that have the catalytic convertor removed or engine code for catalytic converter low efficiency.

Please note this part is an electronic item and does not carry any warranty and is non-refundable. We highly recommend using either the SCT XCal2 or XCal 3, which will perform the same task, but the SCT XCal is more reliable and will help gain more hp and tq.
