03 Town car reference voltage for fuel gauge sending unit and radio illumination

[Dan Dula]

What is the reference voltage for the fuel gauge sending unit. Also the expected resistance, Thanks , my gauge only reads 3/4 at full and about 5 gallons in the tank when gauge reads E and miles to empty = 0. I still get 95 miles til dry. Just bought this beauty and getting to know her peculiarities. Changed out the single cd radio for a 6-cd from an 04 expedition. Needed to rewire for the subwoofer plug and added an illumination feed from the clock. volume is a bit touchy but I can live with it while I clean up some other minor issues. looking to put memory seats in it for the Easy Out feature. LOVE the air ride.
