Frequently Asked Questions About Kenworth T700 Gauges & Switches

Will these gauges and switches fit my specific year model Kenworth T700?

Most aftermarket gauges and switches for the Kenworth T700 are designed to fit models from 2011-2019. However, there can be variations between early production (2011-2013) and later models (2014-2019), particularly in dash panel cutouts and electrical connections. Always verify the specific year range listed for each product, and when in doubt, provide your VIN number when ordering to ensure proper fitment. Some gauge clusters may require different mounting brackets depending on whether you have a standard or premium dash configuration.

Are these gauges plug-and-play, or will I need to splice wires?

This varies by product type. OEM replacement gauges typically feature factory-style connectors that plug directly into your existing harness - no splicing required. However, aftermarket performance gauges or additional gauges often require wire splicing and may need separate power and ground connections. Most toggle switches and rocker switches will require basic wiring unless you're replacing an exact OEM switch. We recommend having a test light or multimeter handy for installation, and many customers find success using add-a-circuit fuse taps for clean power connections.

What's the difference between OEM and aftermarket gauges in terms of accuracy and durability?

OEM gauges are calibrated to work with your truck's existing sending units and typically last 500,000+ miles under normal conditions. Aftermarket gauges from reputable brands like VDO, Auto Meter, and ISSPRO often provide similar or better accuracy but may require their own sending units for optimal performance. The main durability concerns we see involve stepper motors in gauges exposed to extreme vibration. Look for gauges with air-core movements rather than stepper motors if your T700 operates in severe duty applications or rough terrain.

Can I mix different gauge styles or brands in my dash cluster?

Yes, but consider the aesthetic outcome. While mechanically possible, mixing gauge styles (chrome vs black bezels, white vs black faces, different needle colors) can create a mismatched appearance. Many drivers prefer to replace gauges in sets for a uniform look. If you're adding auxiliary gauges, consider gauge pods or panels designed specifically for the T700 dash to maintain a professional appearance. Backlight color compatibility is another consideration - ensure all gauges match your existing dash illumination color (typically amber or white for T700s).

What are the most common installation challenges I should prepare for?

The three main challenges are: (1) Removing the dash bezel without breaking the mounting tabs - use plastic trim tools and work slowly, especially in cold weather when plastic becomes brittle. (2) Accessing the back of the gauge cluster - you may need to remove the steering column shroud and sometimes lower the steering column for clearance. (3) Calibrating aftermarket gauges - temperature and pressure gauges often need adjustment to match your sending units. Have your engine at operating temperature when setting temperature gauge readings, and use a known-good mechanical gauge to verify pressure gauge readings during initial setup.
