DIY Custom Gauges
- 1). Choose your gauges. Some are more expensive than others. Also, determine which gauges you will be installing. Maybe you only want to install a few additional gauges that will monitor functions like oil pressure and oil temperature, or you may want to install an aftermarket tachometer and speedometer as well.
- 2). Determine where you are going to install the gauges. You can use a gauge pod mounted on the A-pillar of the vehicle in the center console by using a gauge panel that screws into place. Depending on the design of the dashboard, you also may be able to install the gauges in place of the stock gauges. If you are installing a tachometer, you can install it in the dashboard. Most gauges come with a mounting bracket that will allow you to mount the gauge on top of the dash or on the steering column as well, giving you multiple options. Wherever you decide to install the gauges, make sure they are easily visible from the driver’s seat.
- 3). Wire the gauges. The gauges will come with detailed directions on how to wire them. Generally, the gauges will have several wires, and will include wires for power, ground and accessory. For a suitable ground, locate a surface that is metal and free of paint. You may need to drill a hole in the metal with an electric drill to allow you to screw the ground wire to the car. Make sure the ground is located near the gauge. For the power, you need to locate an available circuit in the fuse block or splice the wire for the new gauge into an accessory that already has power. To power the lights inside the gauges, locate the wires for the dash lights. Cut the existing wire, strip back the insulation from the end of it and then splice the wire for the gauge light to the wire for the dash light. Connect them with a good-quality bullet connector and wrap the connection with electrical tape.
- 4). Test the gauges once they are wired by turning the car on to make sure they are functioning. If everything is working properly, install the gauges in the locations where you have chosen to install them.
