Quality Michigan Motorsports Product

Allows install of 3 wire heated O2 sensor on cars that came with 1 wires sensors. This will allow proper operation operation with headers which lower exhaust gas temps and may not allow o2 sensor to get up to operating temperature. Just plug in the OEM O2 sensor lead and wire the red lead to a "RUN" switched lead and ground the black wire and you are ready to plug in the AFS74 or equivalent . Very easy install.
