Using this Edge Control Kit is easy. First, install the EAS Starter Kit according to the instructions. Then, place the EAS EGT Probe in the right position to monitor the exhaust gas temperatures. Connect the EAS Power Switch to your accessories like aftermarket lights or air compressors. You can use the CTS/CTS2 device to control these accessories. When using, always keep an eye on the EGT readings, especially when towing heavy loads. High exhaust gas temperatures can cause engine damage. For maintenance, regularly check the connections of the EGT probe and the power switch. Keep the devices clean and dry. If you notice any issues, contact the Edge support team for help.
