A digital gauge gives you live readings for temperature, pressure, voltage, and other systems that are hard to judge by sound or feel alone. Installing one correctly protects wiring, keeps sensors accurate, and helps you catch issues before they cause downtime.
Digital Auto Gauges sells TelTek USA instruments manufactured in the United States. Each eligible gauge includes lifetime warranty coverage when used as directed. Use the PDF links below for the model you purchased. Save a copy to your phone or tablet so the diagrams stay available while you work inside the cab or engine bay.
Before you connect power, confirm the sensor type, wire colors, and mounting location match your vehicle service manual. If a guide is missing for your exact SKU, contact us with your order number and we will send the latest revision.
