I have a Harmar Power chair chairlift. I had no problems getting the power to the lift from the battery. Where the difficulties start is when I plug the two prong license plate light plug into the four prong receptacle. I then get a message that I am towing a trailer and the side proximity warnings have been disabled. Is there another way to get power to the license plate light on the lift so that I can use the proximity sensors? (Picture blurry, but gives an idea of the setup I have.)
