Our Edge EAS accessories are built for Ford Super Duty F-250 and F-350 with 6.7L Power Stroke, Dodge Ram 2500 and 3500 with 6.7L Cummins, Chevy Silverado 2500HD and 3500HD with 6.6L Duramax, and GMC Sierra 2500HD and 3500HD. Whether you need an EAS EGT kit for towing with your diesel truck, an Edge EAS universal sensor input 5 volt for adding custom gauges to your monitor, or an EAS power switch for your Edge tuner, each product plugs directly into the Edge Accessory System for seamless integration with your existing CTS3 or Trinity setup.

EGT Monitoring, Power Cables & Sensor Expansion for Edge Tuners

The EAS EGT kit is critical for diesel truck owners who tow heavy loads — it provides real-time exhaust gas temperature readings directly on your Edge monitor, helping you avoid overheating your turbo and engine during sustained pulls. The EAS power switch adds remote on/off control for aftermarket accessories wired through your Edge system, while the EAS sensor input allows you to connect third-party 0-5 volt sensors for boost, fuel pressure, or transmission temperature monitoring. If your Edge CTS3 replacement power cable is damaged or worn, we carry the exact factory replacement cable compatible with the CTS3, Trinity 2, and TrailDash 3.

For additional diesel performance monitoring, browse our Gauges collection for AutoMeter pyrometer, boost, and transmission temperature gauges with A-pillar pods. Pair your Edge monitor with a cold air intake from Air Intake Systems or an aftermarket exhaust from Exhaust to maximize the performance gains your Edge tuner can measure. For full tuner and programmer options, check out Programmers for Banks Derringer, SCT X4, and Bully Dog units. Browse all diesel performance products under Performance.

Frequently Asked Questions

What is an EAS EGT kit and why do you need one for towing?

An EAS EGT kit connects an exhaust gas temperature probe to your Edge CTS3, Trinity 2, or TrailDash 3 monitor, displaying real-time EGT readings while driving. When towing heavy loads with a diesel truck, exhaust gas temperatures can spike to dangerous levels that damage turbochargers, exhaust manifolds, and engine internals. Monitoring EGT in real time lets you back off the throttle or downshift before temperatures reach critical levels.

Do you need an exhaust gas temperature gauge when towing with a diesel truck?

An exhaust gas temperature gauge is one of the most important additions for any diesel truck that tows regularly. Sustained heavy loads on grades and highways can push EGTs well beyond safe operating ranges — especially on Cummins 6.7L, Power Stroke 6.7L, and Duramax 6.6L engines. An EGT gauge gives you the data to protect your engine and turbo before damage occurs, rather than relying on warning lights that may trigger too late.

What accessories are compatible with the Edge CTS3 performance monitor?

The Edge CTS3 is compatible with the full Edge Accessory System lineup, including the EAS EGT kit, EAS power switch, EAS universal sensor input 5 volt, and EAS replacement power cables. Multiple EAS accessories can be daisy-chained together on a single CTS3 monitor, allowing you to run EGT monitoring, boost pressure, and custom sensor inputs simultaneously from one screen.

What does the EAS universal sensor input do on an Edge tuner?

The EAS universal sensor input accepts any 0-5 volt third-party sensor and displays the readings directly on your Edge monitor alongside your other gauges. This allows you to add boost pressure, fuel pressure, transmission temperature, oil temperature, or any other sensor that outputs a 0-5 volt signal — without needing a separate standalone gauge or display in your cab.

What is a safe exhaust gas temperature when towing heavy loads?

Safe EGT levels vary by engine, but as a general guideline, sustained exhaust gas temperatures above 1,200°F to 1,300°F are considered the upper safe limit for most diesel trucks. Momentary spikes during hard pulls are normal, but sustained temperatures above this range can cause turbo damage, cracked exhaust manifolds, and piston failure. An EAS EGT kit lets you monitor these temperatures in real time and adjust driving behavior before reaching dangerous thresholds.

How do I replace the power cable on an Edge CTS3 or Trinity tuner?

The Edge CTS3 replacement power cable is a direct plug-and-play swap — unplug the old cable from the OBD-II port and the monitor, then connect the new cable to both ends. No tools or reprogramming required. The replacement cable is compatible with the CTS3, Trinity 2, and TrailDash 3 monitors and restores full power and data connection between the OBD-II port and your Edge monitor.
