Here's how we determine if the problem is the converter box of the trailer wiring harness you have installed on your 2016 Ford Edge.Test the wire green wire that runs to the converter box from where it attaches to the vehicle wiring. If there is voltage there with the blinker but it's weak on the other side of the box then the box is faulty.
I suspect it is the converter box, but if you can test that for me we'll know for sure.
