Frequently Asked Questions About International 9300/9370 Gauges & Switches

Will these gauges and switches fit my specific International 9300 or 9370 model year?

Most gauges and switches for International 9300/9370 trucks are compatible with models from 1987 through 2007. However, there are some variations between early models (1987-1994) and later models (1995-2007), particularly in electrical connections and mounting configurations. Always verify the specific years listed in each product description, and if you're unsure, contact us with your truck's VIN or year for confirmation.

Are these aftermarket gauges as accurate and durable as OEM parts?

Quality aftermarket gauges from reputable manufacturers like VDO, Stewart Warner, and Kenworth use the same sensor technology and often the same suppliers as OEM parts. They typically feature brass housings, sealed bezels, and automotive-grade electrical components that meet or exceed OEM specifications. Most come with 1-2 year warranties and are tested to withstand vibration, temperature extremes, and moisture common in commercial trucking applications.

What tools and skills do I need to install gauges and switches myself?

Basic gauge replacement requires standard hand tools including screwdrivers, socket sets, and wire crimpers. Most installations take 30-60 minutes per gauge. You'll need basic electrical knowledge to connect power, ground, and signal wires correctly. Switches typically require drilling mounting holes if replacing a different style. We recommend having a multimeter for testing connections and always disconnecting the battery before starting electrical work.

What's the difference between mechanical and electrical gauges for my application?

Mechanical gauges use direct physical connections (like capillary tubes for temperature or bourdon tubes for pressure) and don't require power to operate, making them extremely reliable but limited in mounting locations. Electrical gauges use sending units and can be mounted anywhere but require proper grounding and voltage. Most International 9300/9370 trucks came with electrical gauges from the factory, making electrical replacements the easier swap in most cases.

Do these replacement switches include the correct connectors and will they match my dash lighting?

Most replacement switches come with standard blade terminals that work with existing International wiring harnesses, though some may require crimp-on connectors (usually included). For illumination, look for switches specifically marked as "backlit" or "illuminated" - these are designed to work with your truck's 12V dash lighting system and will match the amber/orange glow of International dashboards. Non-illuminated switches are also available if backlighting isn't needed.
