That sounds like the turn signal wire should be swapped back. Then sort out why the indicator light is not getting a voltage. There is a very good "Tech Tip" on how your switch is hooked up. Mine is the old style and has fewer wires and 2 indicator lights. Requires separate lights for the signals. So I have 2 tail lights on each side of the truck at the back. One is for brake lights and the other is for signals. But the tech tip is for your type of switch that integrates the brake and turn circuits. Happy hunting.
