Onan EC-AGS+ compatibility model prep

Use the official Cummins Onan EC-AGS+ compatibility chart to collect generator, harness, and kit-compatibility details before support.

Owner-safe checklist

Record the EC-AGS or AGS+ kit, generator model, spec letter, serial number, RV make and model, air-conditioner control type, and exact compatibility question.
Save photos of the generator label, AGS display or module label, purchase paperwork, and the chart row you plan to reference.
Use Cummins Onan, Coach Care, an authorized service provider, or qualified generator service for compatibility, installed power, auto-start setup, parts, or repair decisions.
