i am fitting an engine preheater to my xm but need to find a safe way of plugging it into the mains. my plan is to fit a socket to the front of the car underneath the bumper...but obviously it needs to fit flush and be waterproof to the on slaught of winter weather. so maybe it needs a flap that flaps over the fitting when not in use. anyone know where i may get one of these?
