The EAS 98609 Power Switch w/ Starter Kit allows you to hook up and engage accessories such as aftermarket lights, air compressors, etc. right from the CTS device. Install the new switch, then use Edge's MyStyle software and name your accessory to display right on the screen. You can also take advantage of Edge's clean EAS daisy chain link system to turn your truck's tools on/off. The EAS Power Switch can control two accessories per each switch.
