I found my AEM 30-4100 in a box in the basement today. It is in very good condition. It will come as you see it, already installed in the dash trim piece that goes below the vent to the left of the radio. It includes the gauge, dash trim piece, power harness, and sensor harness. It does not come with the sensor itself. The sensor is pn 30-2001 and can be bought from Amazon for 75 dollars. If anyone is interested you can have it for 50 bucks shipped.
