The stock cluster has some kind of formula involving the level sensor and amount of fuel injected to derive a displayed value, if fuel injected amount is not supplied then the car will be bone dry at an apparent 1/3rd tank on the cluster. This applies to Gen 1, I know nothing about Gen 2.

You can do two things. stick the OEM cluster in the back or something and then hace the IC7 mounted infront of it. Or two, you can hook up the fuel level sensor directly to the IC7. But it wont be as fancy to give you a accurate reading like the OEM. Yeah OEM use both fuel injection timing and a average of the level sensor to determine the real level. without the injection Pulse with the oem cluster would have a funky operation that at 1/4th tank the gas would be actually empty. But this isnt a issue if you hook up the IC7 directly to the sensor. As long as it had a good algorithm for averaging the sensor input reading.
