Frequently Asked Questions About Freightliner FLC112 Gauges & Switches

Will these gauges and switches fit my Freightliner FLC112?

Products in this category are designed to fit the Freightliner FLC112, but dash configurations can vary depending on the model year and how the truck was originally optioned from the factory. Before ordering, check the part number and dimensions against your existing gauge or switch, and reach out to our team if you are unsure whether a specific item matches your truck's setup.

Are these OEM parts or aftermarket replacements?

This category includes a mix of OEM and quality aftermarket gauges and switches. Each product listing specifies whether the part is OEM or aftermarket, along with the manufacturer, so you can choose based on your preference for factory-original equipment or a more budget-friendly alternative.

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

Most gauges and switches are designed for straightforward installation using the existing wiring harness and dash mounting points. Always disconnect the battery before working on the electrical system, and take note of existing wire positions or take photos before removing the old part. If a gauge requires calibration or a specific sender unit to function correctly, that information will be noted on the product page.

How do I know which switch or gauge I actually need?

The best way to confirm the correct part is to compare the physical switch or gauge you are replacing against the images and specifications listed, including button style, wiring connector type, and gauge face markings. If your original part has a part number stamped or printed on it, that is the most reliable way to find an exact match.

Do these gauges and switches come with any warranty or support if there's an issue?

Warranty coverage varies by manufacturer and is listed on each individual product page. If a gauge or switch arrives damaged or does not perform as expected, contact our customer service team so we can help troubleshoot the issue or process a return or exchange according to the applicable warranty terms.
