The EAS 12 Volt Power Kit enables the Trinity 2 MX to work with vehicles that do not have an OBDII port! By connecting to a key-switch power and ground source the T2 becomes a digital gauge display for anything that you want to monitor! With the separate purchase of the EAS system, you can monitor EGTs, pressure readings, temperature readings, and much more. Check out the EAS kits for expanding your monitoring options on the T2 MX. The T2 MX paired with the EAS system allows you to build a custom gauge display on your ride and data log seamlessly.
