The instructions are pretty good, but when it indicates to Press and Hold the calibration button to see the needle move, keep your finger on the button to get the needle to move. When the needle is moving in- between quarter marks release the button otherwise it is easy to over shoot the mark. It doesn't take long holding the button to get the needle to move so I would not keep pressing and then releasing the calibration button quickly otherwise the needle will not move in the correct direction and just oscillate. When you are done calibrating Full do not press the calibration button within 8 secs it will change to "C" indicating the calibration is saved. To Exit Calibration mode, and while the LED indicates "C", press and hold the calibration button. The LED will then go blank. The entire calibration took less than 5 minutes.

I have a 1968 dodge coronet converted to a '68 chargwe tank and filler. Yes the filler is now atop the fender instead of behind the license plate. Can I use this calibrator to set my fuel guage. Thanks- Brian Stern

I have a 2005 Mustang GT, I put a 2014 Mustang GT tank in (lighter, better fuel pumps) will this correct my fuel gage issue? It reads backwards and resets itself to empty continually. I know both years ohm resistance are different but I can't find any wiring schematics to rectify this situation manually so I have been looking high and low and came across this box.

Can SN34 be installed near the sending unit opposed to under the dash next to the fuel gauge? I don't believe I have the space under the dash.

Are you able to explain what is used for a low fuel indicator and how it is wired. The instructions for the SN34 do not appear to provide this detail. Similar products explain that a relay is required for a lamp but a led can be connected directly. This unit appears to provide power and ground for the low fuel indicator which could imply a lamp can be connected directly to the unit. Grateful clarification.
