Hi Peter! The Soft Start Kit for Coleman-Mach RV Air Conditioners # CM56RR is what you need. This is designed to fit Coleman-Mach Series 45000, 47000, and 48000 AC units. The 48204-669 you have falls under the 48000 so they are compatible.
Where are you headed with the Reflection once you get the soft start installed?
