There is the red wire, that goes to +. The + can be switched or constant. I attached the unit to constant +, so it is always under power. I know i could have done different, but this hangs up the empeg more often. When the car is started, the switched + is disconnected as long as you use the starter, like 1 second or so. This seems to be to short for the unit to go into a defined mode, so when the power comes back, the unit is hung, the LED ist constantly on and nothing happens. I have to put the unit out and back in to get it back working.

So what is the right connection ? Constant or switched + ?
