Re: Add water Temp Gauge,Need help.

Use the search feature as this has been covered many times. You don't "pluimb" a temp gauge. You add the temp sender to the engine, run a wire from the sender to the "S" terminal on the gauge, connect the "I" terminal on the gauge to the "I" terminal on any other gauge and connect the ground terminal to the ground terminal on any other gauge. If you want the light to work, connect the "L" terminal on the gauge to the "L" terminal on any other gauge. Buy the gauge and sender together. They must match. Most gauges use a 33-240 ohm sender.
