Brakes sometimes work sometimes don't
My electric brakes work when barley rolling like at a stop light or backing into a site but when traveling at any speed the controller flashes red and dont work. Ive already added grounds to both ends...

What kind of controller? My first reaction would be the controller isn't working correctly. Maybe you can borrow someone's controller for a couple of hours to see if that makes a difference. Other obvious troubleshooting step is to check the truck end of the plug to see if current flows when you step on the brakes; although having said "barely moving" it works, that is probably not going to provide a definitive answer.
