Peterbilt 567/579 Toggle Extensions

Frequently Asked Questions About Peterbilt 567/579 Toggle Extensions

What are Peterbilt 567/579 toggle extensions used for?

Toggle extensions are add-on switch panels that mount to the dash of your Peterbilt 567 or 579, giving you additional toggle switch positions beyond what came standard from the factory. They're commonly used to wire in extra accessories like auxiliary lights, fans, or other electrical add-ons without cutting into the factory dash panel.

Will a toggle extension fit my specific dash setup?

Toggle extensions are designed to match the factory dash contours of the Peterbilt 567 and 579, but panel styles, cutout counts, and switch hole sizing can vary between manufacturers and model years. Check the listed fitment details and switch cutout specs before ordering to make sure it matches your truck's dash configuration and the switches you plan to install.

Do these extensions come with switches included, or just the mounting panel?

This varies by product. Some toggle extensions are sold as a blank or pre-cut panel only, while others include switches, wiring, or mounting hardware. Always check the product description carefully so you know exactly what's included before you buy, and plan accordingly if you need to source switches or wiring separately.

What materials and finishes are available?

Toggle extensions are typically offered in materials like stainless steel or durable plastic/composite panels, with finish options ranging from brushed stainless to painted or textured black finishes. Choosing a finish that matches your existing dash trim will give the cleanest, most factory-look result.

How difficult is it to install a toggle extension myself?

Installation difficulty depends on the specific product, but most toggle extensions are designed to mount using existing dash mounting points or simple adhesive/screw attachment, with basic wiring required if switches aren't pre-installed. Anyone comfortable with basic hand tools and simple 12-volt wiring should be able to install one, though wiring in additional circuits may require a fused connection to your truck's power source.
