MAXTOW EXPANDABLE CIRCUITS FOR 12 VOLT ACCESSORIES
MaxTow Expandable Circuit Fuses are designed for powering 2-1/16” (52mm) Double Vision™ truck gauges by reducing installation time and removing the need to tap into your truck’s existing wiring. Utilize your vehicle’s fuse box to effortlessly connect virtually any 12v accessory by running the power wiring that comes with each gauge or other accessory directly through it. We recommend choosing a non-vital fuse source to power your gauge or accessory.
WHAT KIND OF EXPANDABLE CIRCUIT FUSES DO YOU HAVE?
MaxTow has several different sizes available to choose from, including an ATO ATC Expandable Circuit, Mini Fuse Expandable Circuit, Micro2 Expandable Circuit and more. Each version includes a 4 Amp Fuse and (2) Expandable Circuit Fuse spots. A maximum of (4) gauges can be used with each Expandable Circuit. Multiple circuits are also required for connecting to each constant (un-switched), ignition (switched) and headlight switched 12 volt source.
FIND THE RIGHT EXPANDABLE CIRCUIT FOR YOUR TRUCK
Check your truck owner's manual or fuse panel before ordering to determine which size will be applicable for your specific application. Selecting the right Expandable Circuit Fuse involves matching the size of the fuse to the size of the Expandable Circuit with the corresponding dimensions. With several different versions available, you’re sure to find the right size for your gas or diesel truck. All you will need for installation is a wire stripper and wire crimper. Installation instructions are also provided to walk you through the process step by step.
How Do MaxTow Expandable Circuit Fuses Simplify Truck Gauge Installation?
Each expandable circuit includes a 4 Amp fuse and 2 plug-and-play spots, allowing you to connect up to 4 Double Vision® and MaxTow Match truck gauges or accessories quickly. By tapping into a non-vital fuse, you can safely run power without permanent modifications or complex wiring.
What Are the Benefits of Using MaxTow Expandable Circuits for Truck Gauges and Accessories?
MaxTow Expandable Circuit Fuses let you power truck gauges and 12 volt accessories directly from your make and model’s fuse panel. They eliminate cutting or splicing factory wiring, simplify installation, and provide clean, reliable connections for multiple accessories with minimal effort.
Are MaxTow Expandable Circuit Fuses Compatible with All Trucks?
Yes. They come in multiple types—ATO ATC, Mini Fuse, Micro2 and more—to match various fuse panel sizes. With proper selection based on your truck’s manual and included step-by-step instructions, installation is straightforward for both gas and diesel applications.
