Peterbilt 359 Gauges & Switches

Frequently Asked Questions About Peterbilt 359 Gauges & Switches

Will these gauges and switches fit my Peterbilt 359?

Most gauges and switches in this category are designed to match the factory dash configuration of the Peterbilt 359, but panel styles, mounting hole sizes, and wiring connectors can vary by production year. Check the product listing for specific fitment notes or year ranges, and compare your existing gauge or switch dimensions before ordering to ensure a proper match.

Are these replacement parts OEM or aftermarket?

This category includes a mix of OEM-style replacements and aftermarket gauges and switches. Aftermarket options are built to closely match the look and function of factory components, often at a lower cost. If having an exact OEM match is important to you, check the product description or reach out to our team to confirm the part's origin before purchasing.

What types of gauges and switches are included in this category?

You will find items such as speedometers, tachometers, oil pressure and temperature gauges, air pressure gauges, voltmeters, and various dash switches for lights, wipers, engine brakes, and accessories. Bezels, lenses, and mounting hardware for these components may also be available.

Do I need any special tools or wiring knowledge to install these?

Basic hand tools such as screwdrivers and pliers are typically sufficient for swapping out a gauge or switch, but some installations involve connecting to existing wiring harnesses. If you are not comfortable working with electrical connections or diagnosing wiring issues, we recommend having a qualified diesel technician handle the installation to avoid damaging your dash electronics.

What should I check if my new gauge or switch is not working correctly?

First, verify that all wiring connections are secure and matched to the correct terminals, since many gauges and switches use similar-looking connectors. Next, check the fuse or circuit breaker associated with that component. If the part still does not function after confirming proper installation and power supply, contact our customer service team so we can help troubleshoot or process a warranty claim if applicable.
