MaxTow’s Micro2 Expandable Circuit allows you to easily connect additional 12-Volt accessories to an existing fuse holder without the need for cutting or splicing your vehicle’s existing wiring. The 3/8” wide expandable circuit offers plug and play connectivity and is designed to provide two fuse spots: one for your vehicle’s existing fuse up to 15 Amps, and another for the included 4-Amp fuse. It is also ideal for connecting MaxTow Fuel Pressure and Volt gauges, as well as all of your popular gauge types. All mounting hardware and installation instructions are included with every Micro2 Expandable Circuit purchase, along with a one year limited warranty and free lifetime technical support. Get ready to hit the road and Tow to the Max™!
