So I got pulled over for not having tail lights. Soon after, I noticed it would run rough and die when braking, using turn signal, putting in reverse. If I pull the harness connector at the rear loose, it runs like a champ. Also, the turn signal flashes fast and it doesn't matter if the harness is hooked up or not. replaced the rear light boards and no change. If I turn the headlights on it runs ok until I press the brakes. Any ideas what is causing this? anyone else have this happen? Any help is appreciated.
