How to install the electric water temp gauge with the original vehicle? The 12V electronic water temperature gauge is connected to the key, and then the sensing plug is connected to the water channel. External water temperature gauge set, with instrument, harness, sensor and other accessories. The body of the water temperature gauge is self luminous on a white background, which is suitable for observing water temperature at night.

There are four lines in total, one of which is a three line instrument. The focus is on the four line instrument. The four lines are red (open key 12V), black (ground wire), blue (signal line), and white (power is available when the small light is turned on). The three line instrument is short of white lighting line.

The engine electric water temp gauge is used to indicate the temperature of the engine coolant. The coolant temperature signal is provided by the engine coolant temperature sensor installed on the engine cylinder head. When the engine works normally, the displayed value should be 80-100 ℃. When the engine coolant temperature reaches 97 ℃, the cooling fan runs at low speed. When the engine coolant temperature is lower than 94 ℃, the cooling fan stops running. When the engine coolant temperature is higher than 105 ℃, the cooling fan runs at high speed. When the engine coolant temperature is lower than 101 ℃, the cooling fan stops running.

One of the sensor of the electric water temp gauge, and the other is a wire, which is used to display the temperature of the cooling water (or coolant) on the water temperature gauge and adjust the fuel supply during startup . The other is a sensor for cooling water or coolant, which is a two-wire sensor. The coolant sensor is used to control the electronic fan. The electronic fan will work when the temperature is high.

Red or red black is connected to the positive pole of the key switch and black negative pole. Two black and white or two-color long wires are connected to the inductor. Install the inductor on the position of the inductor on the original engine. First of all, a live wire is the positive wire into the positive end of the instrument, and a wire from the negative end of the instrument to the water temperature sensing plug. There is a mark near the pile head of the watch. The black grounding wire and the yellow or white sensing plug wire are marked. You should know that there is only one pile head.
