This is a tremendous new feature for truck owners! Customers can now hook up accessories like aftermarket lights, air compressors, etc. and engage them from the CTS. Install the new switch and use Edge's MyStyle software to name your accessory to display right on the screen and 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. *This kit is offered two ways, with (98609) or without (98619) the required Starter Cable. Sku 98619 does not include the Starter Cable, for those already running EAS accessories, like our EGT probe kit, who would already have the Starter Cable needed to implement this switch kit. If you don't currently run any EAS accessories with your device, you'll want to purchase the kit WITH start cable, 98609.
