Neal, whenever you see that the app for the Curt Echo # C51180 is saying that the 7-way is disconnected, and it isn't, the problem is usually with the 7-way. I'd start by checking both the vehicle and trailer side and make sure that there are no bent pins or corrosion.

Hey Neal, did checking the 7-way plug on both the vehicle and trailer sides clear up the disconnect message in the Curt Echo app? Your update could make it easier for others who run into the same issue.
