The AccuAir ENDO Compressor Analog Adapter Harness is used to connect the AccuAir ENDO Compressor (sold separately) to your existing ENDO-T or ENDO-VT system. The AccuAir ENDO Compressor Analog Adapter Harness is also required to connect AccuAir eLevel to a CVT tank. ENDO valves cannot be controlled without it. For example, if you currently have AccuAir eLevel management and want to add a CVT tank you must purchase this Adapter.
The LED on this box tells you how the compressor is operating and if there are any errors. It is not required if you use an ENDO-CT with any non Accuair control system. It can be beneficial for the use of the status LED.
