Volvo WIA Gauges & Switches

Frequently Asked Questions About Volvo WIA Gauges & Switches

Will these gauges and switches fit my Volvo truck model?

These gauges and switches are designed to match the WIA (Volvo's part numbering prefix) specifications used in specific Volvo VN, VNL, and VNM series trucks. Because dash configurations and electrical systems can vary by model year and trim, we recommend checking the part number on your existing gauge or switch, or referencing your truck's VIN and build sheet, before ordering to confirm a proper fit.

Are these OEM parts or aftermarket replacements?

Our Volvo WIA gauges and switches are sourced to match OEM specifications for fit, function, and appearance. This helps ensure they integrate with your existing dash panel and wiring harness without requiring modifications.

What do I need to know before installing a replacement gauge or switch?

Before installation, disconnect the battery to avoid electrical shorts, and take note of how the existing wiring harness connects to the back of the gauge or switch. Most WIA gauges and switches use a plug-and-play connector that matches the factory harness, but always compare the old and new parts side by side to confirm the pinout and connector style match before installing.

How do I know if my gauge or switch is actually faulty versus a wiring or sensor issue?

Gauges and switches can appear faulty even when the real issue lies with a sensor, fuse, or wiring connection elsewhere in the truck. If a gauge reads incorrectly or a switch fails to activate its function, check the related fuse and sensor connections first. If those test fine and the problem persists, the gauge or switch itself is likely the cause.

What is the difference between a switch and a gauge in this category?

Gauges display readings such as fuel level, oil pressure, temperature, or voltage, giving the driver ongoing information about truck systems. Switches control functions like lights, wipers, or auxiliary equipment by completing or breaking an electrical circuit. Both are dash-mounted components, but they serve distinct roles in monitoring versus controlling your truck's systems.
