Redpaddy: Overheating? Not sure that I understand. The protective element in the circuit (fuse) will limit the current to any device that is connected to the cigarette lighter to no more than 20Amps (i.e. the rated capacity of the circuit's wiring and any upstream components such as connectors and relay contacts). About the only concern that I would have would be the long term drain on the battery should a device be connected for an extended length of time. But assuming that westy uses his/her car regularly and that the current drain from his son's iphone is not large, I wouldn't be worried. Also, given that it looks like the design of the fuse board is purposely intended to allow fuse #40 to be moved to the top position, I fully anticipate that the safety of the car's electrical design will not be compromised by this change. And besides that, it's such an elegantly simple tweak!!
