    I have the 13577379 and wired it per the directions, and as it's drawn out on the white board. No, my sensor came with the correct paperwork, but didn't have the markings on it. I didn't want to blame the sensor if there was a chance that I had made a wiring mistake; it happens on occasion.

    But you posted the Continental sensor pin-out in post #17.

    I've tried every pin-out combination listed.

    Once you replaced the sensor, did you wire everything the way you depict on the your whiteboard drawing?

    I believe so, it became very confusing because I kept swapping everything around trying to make it work. When my new sensor came in, I put it all back to the way I understood it needed to be wired and it worked.

    Danny, can you confirm the wiring is correct as depicted in post #10?

    It depends on which flex fuel sensor you have. It seems the Holley instructions are correct for that AEM Flex Fuel sensor, but wrong for Continental 13577379 Flex Fuel sensor.

    Disregarding the fuel sensor type, since I have the pin-out for my sensor. I just want to make sure the sensor input and the 5V with the 10K Ohm is wired correctly in that picture. I'm probably over thinking it, but looking at the Holley instructions, it kind of looks like both wires continue on when in the picture the 5V terminates at the 10K Ohm resistor. I should have been more clear in my first post.
