AFS-74 to Grand National Wiring Adapter

This plug-in adapter is used when you are installing an AC DELCO heated Oxyen sensor into a retrofit application where a one-wire sensor was originally used. Plugs into the 3 cavity Weatherpack connector on the AFS-74 sensor and provides two heater feed wires; one red and one black. Wires must be spliced into existing positive feed and ground

NOTE: Does not include AFS-74 sensor - available from GM.
