mghmghmghusa did you ever identify an adapter?
There's one module you plug into the 'cigarette lighter' to set/vary the braking force to match the weight of your trailer. The actual controller just plugs into the 7 way connector on the back of the car. Once you set the force you don't actually need the module inside the car anymore but I like to keep in plugged in when I tow because it will confirm the controller is actively working.
