You will be able to replace your Coleman Mach 48254A866 with the Advent # ACM150 provided you use the Wiring Kit # ACCOLKIT. This wiring kit adapts the 6-pin wiring on the Advent to the 9-pin connection used on your Coleman control box.

Hey, how did the replacement go with the Advent AC and the wiring kit on your Jayco Jay Flight? Did everything connect smoothly with your existing control box? Your update could make it easier for others working on the same swap.
