    Good news is that It works perfectly and I will definately recommend others to purchase from you. But . . . I had to swap pins D and E so the sensor matched the existing Holley harness. Not sure if I have a unique wire harness or if the sensor was simply wired incorrectly. The attached photo shows the pin out for my exixting Holley sensors and the one I bought from you. Very happy with the sensor and thanks for the great service.
