To convert a car dashboard to digital, remove the dash cover. Install the new gauges according to the instructions provided with the kit, and calibrate the gauges using a calibration tool, or use the calibration button on the gauge if it is available. Connect the new digital displays to the control module, and connect the wiring to the recommended places on the engine.
Refer to the specific calibration numbers for the vehicle's make and model to adjust the gauges properly. Some vehicles require setting the new gauge manually. Install the control module in a protected location on or under the dash.
When placing the new displays in the trim assembly, hold the wires out of the way to prevent trapping them between the display and the trim piece. To connect the sensors, strip the appropriate wire, and connect the wire to the sensor before installing the sensor on the engine.
Refer to the instructions included in the conversion kit to determine where to place each wire on the engine, as some gauges have multiple connection points and others can be connected to a variety of areas. Use the recommended adaptor to install the temperature sensor on the engine properly, as the kit may contain a wide assortment of adaptors.
