I have a 19' proline sport with a Suzuki DF115. Faria gauges were installed from the factory. I bought a matching Faria trim gauge. After wiring, found gauge doesn't work. I can make the gauge sweep by jumping black wire from sender to ground. (i know the gauge works) Do I need a different sender other than the factory suzuki sender for this to work? 2 wire sender comes from the engine to console, doesn't make sense to me.
