What Is a GlowShift Expandable Circuit?
Our Expandable Circuits are designed for powering GlowShift gauges by reducing installation time and removing the need to tap into your car or truck’s existing wiring. You can utilize your vehicle’s fuse box to effortlessly connect GlowShift 12 volt products by running the power wiring that comes with each gauge directly through it. Several different versions are available that include 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 sources.
Easier Installation with GlowShift Expandable Circuits
Using an Expandable Circuit will make powering gauges much easier and eliminate the lengthy process of having to cut and splice wires. 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. Before getting started, disconnect the negative side of your vehicle’s battery. Connect the ground wire from your gauge to a reliable ground source or bare metal location. Insert the lead power wire into the open end of the blue butt connector on the red wire attached to the Expandable Circuit. After the lead wire is inserted into the butt connector, use a crimping tool to crimp the butt connector and secure the connection. Then locate your fuse panel and select a fuse that does not exceed 15 amps to power your gauge. This may be a constant (un-switched), an ignition (switched) and/or headlight switched 12 volt source, depending on the installation location you choose. Also make sure to choose a non-vital fuse source to power your gauge. Next remove the fuse from the fuse panel where you have chosen to bridge power. Then plug the fuse you just removed into the open fuse socket of the Expandable Circuit. Replace the fuse you removed from your fuse panel by inserting the circuit in its place in the empty spot.
Find the Right GlowShift Expandable Circuit for Your Installation
GlowShift has several different sizes available to choose from, including an ATO ATC Expandable Circuit, Mini Fuse Expandable Circuit, Micro2 Expandable Circuit and more. Check with your car or truck's owner's manual or fuse panel before ordering to determine which size will be applicable for your specific application. Selecting the right size essentially depends on matching the actual size of the fuse to the size of the Expandable Circuit which has the corresponding dimensions.
