Hi Richard; I'm assuming the screen doesn't even turn on when you plug it in. If that is correct, check for power on the E-450 wiring harness. It could be that you have a blown fuse or the fuse is missing for the brake controller wiring which would explain why nothing happens.

There is power to the plug

@Richard if you have power at the plug and the brake controller screen won't turn on it is probably a problem with the brake controller. I would reach out to the manufacturer or whoever you bought it from to see about replacing it under warranty.
