    Default Need wiring schematic for LC-2 O2 sensor harness

    Help. I purchased a new innovate LC-2 that arrived w/o the O2 sensor. I have a compatible "017" O2 sensor with no connector that I need to adapt and I want to confirm the pinouts for the cable. Does anyone know the correct pinouts? Any help would be appreciated.

    we require the wiring schematics of the sensor cable used in lc-2.
    I you have one can you just check the continuity and provide us which pins on sensor end connect to which pins on the lc-2 end.

    pin 2 on the lc 2 side is for shielding the wire to prevent interference.
    there were 6 wire connecting the terminals. out the six only 4 wires were twisted and shielded. The other two wires is for the heater in the oxygen sensor and it was made of higher gauge wires.
    Interestingly out of the 4 signal wires two were of the same color and terminated on to the pin 5 on the sensor side i hope. I think this is to pair the wires to get cleaner signals
    Pin 6 on the sensor side was blank.
