We have a Dodge Journey that we'll tow using a Acme EzTow if we get a Super C. The weight is about 4,100 but with the dolly it will come in around 4,300 so we should end up close to the same when it's all done.
I think the Jeep cable converts the standard 4 pin trailer signals to CAN bus instructions to the Body Control Computer on the Jeep. It would be nice if that controller would work the Journeys BCC but that would be a very, very, very long shot.
No one to date has made a standalone controller to do the same thing for other vehicles but I've designed a system that will connect into the lighting connectors so it will basically do the same thing but just not as elegant. By using mating connectors inline with the lights it can be removed at any time incase any servicing needs to be done.
