Frequently Asked Questions About Kenworth Cabover Gauges & Switches

Will these gauges fit my K100, K100E, or older W900 cabover model?

Most of our Kenworth cabover gauges are designed to fit K100 and K100E models from 1963-1989. However, gauge hole sizes can vary between early and late production years. Standard 2-1/16" gauges typically fit most models, but pre-1976 trucks may have different mounting requirements. We recommend measuring your existing gauge holes before ordering. For W900A cabovers (pre-1982), some modification to the dash panel may be required for proper fitment.

Are these gauges direct plug-and-play replacements, or will I need to rewire?

While many of our gauges use standard SAE connections that match original Kenworth wiring, some aftermarket upgrades may require minor wiring modifications. Mechanical gauges (oil pressure, water temp) will need new sending units and tubing routed from the engine. Electric gauges typically connect to existing sending units but may need adapter harnesses for older trucks. Each product listing specifies whether additional wiring or sending units are needed.

What's the difference between mechanical and electric gauges, and which should I choose?

Mechanical gauges use direct pressure lines or capillary tubes and provide instant, accurate readings without electrical interference. They're ideal for critical readings like oil pressure but require routing lines through the firewall. Electric gauges use sending units and are easier to install but depend on good electrical connections. Most drivers prefer mechanical for oil pressure and temperature, and electric for voltmeters and fuel gauges. Consider your comfort level with installation complexity when choosing.

Do you offer complete gauge sets that match in style and lighting?

Yes, we carry matching gauge sets from manufacturers like VDO, Auto Meter, and Stewart Warner in various styles including chrome bezels, black faces, and white faces. Most sets include consistent backlighting (usually green or amber) and matching needle styles. Popular complete sets include 6-gauge panels with speedometer, tachometer, oil pressure, water temperature, voltmeter, and fuel gauge. Individual gauges from the same product line will match if you prefer to build your own custom setup.

How difficult is it to replace toggle switches and rocker switches in the dash?

Replacing switches in Kenworth cabovers is generally straightforward but varies by location. Dash-mounted switches typically pop out from behind after removing the dash panel screws. Most use standard spade terminals that match original wiring. The main challenges are accessing switches behind the dash (especially near the center) and ensuring proper amp ratings for your accessories. Heavy-duty 20-30 amp switches are recommended for items like auxiliary lights or air accessories. Always disconnect the battery before switch replacement to avoid shorts.
