Voltage limiter

Hello I bought this voltage limiter for my 68 newport as the gas gauge is not working. The ground on the new sending unit has been replaced used a test light behind the cluster, there is power going to one side of the gauge and not the other. Now besides the limiter there is a cylinder type resistor on the back right near the voltage limiter. I cannot find the exact limiter like the one on the cluster but purchased this one from standard as it says it fits 77-65 chrysler autos. Here is the pic. I am at a stand still now please help sorry for the new threads.
