Kenworth T660 Gauges & Switches

Frequently Asked Questions About Kenworth T660 Gauges & Switches

Will these gauges and switches fit my Kenworth T660 without modification?

Most gauges and switches in this category are designed to match the factory dash layout and wiring configuration used in the Kenworth T660. However, production year and dash configuration can vary, so it's important to check the specific fitment notes on each product page and compare part numbers with your existing components before ordering.

Can I install a new gauge or switch myself, or do I need a professional?

Many drivers and owner-operators replace gauges and switches themselves since the process typically involves basic tools, disconnecting the old unit, and wiring in the replacement. That said, if you're not comfortable working with electrical connections or your dash has custom wiring, having a qualified technician handle the installation is a safer option.

What is the difference between OEM and aftermarket gauges or switches?

OEM parts are made to match the exact specifications and appearance of what originally came in your T660, while aftermarket options can offer similar function at a different price point or with variations in styling. Both can be reliable choices, but OEM parts generally provide the closest match for fit, finish, and long-term compatibility with factory wiring.

How do I know if a gauge is reading incorrectly versus a wiring or sensor issue?

If a gauge shows erratic readings, stays at zero, or maxes out unexpectedly, the issue could be the gauge itself, a faulty sensor, or a wiring problem. Before replacing the gauge, it's a good idea to check the related sensor and wiring connections, since a straightforward gauge swap won't solve an underlying electrical or sensor fault.

Do these switches and gauges come with any warranty or quality assurance?

Warranty coverage varies by manufacturer and part, so we recommend checking the specific product listing for warranty details before purchasing. If you have questions about a particular gauge or switch, our team can help clarify what coverage applies.
