Hook to the black one

thanks pete
Best to hook the A/F gauge wire to the harness side of the 02 wiring, not the wiring from the connector to the sensor, because if you have to replace the sensor, you will have to redo the gauge wire too. Hook up to the Dark Green / Pink wire in the harness at the 02 connector, or at the EEC, pin 28 (that way you dont have to run a wire thru the firewall).
