Oh well pzsasdafdsadsfewfoqwel.s............................................................ That's first thing you gotta do......................
Also some (like SW) aftermarket gauges are what are called a "bridge." This means that the gauge either has a ground terminal or the case MUST be grounded. "Bridge" type meters actually have 3 terminals.........hot coming in (usually right off battery NOT through a factory IVR, the sender terminal and the ground to the bridge
Jus' sayin...........find out what you have and heed.
Example of a bridge type circuit...........quite different from factory Mopar
