5 volt resistor for gauges

The plug in type are for dart standard dashes, maybe Valiant and probably other B, C, E bodies.

The Ralley dashes have the IVR inside the fuel gauge. It is not removable.

You can replace the fuel gauge with a good used one maybe a repo.

Or you follow the instructions on the r-t engineering website and disable the bad IVR in the fuel gauge and add a external one.
