To avoid having trailing cables to the sat nav I decided to install a PS permanently. Siting a 2.5mm power socket on the top of the dash. Cutting into the output cable discovered it has three wires - black red and white. The black and red are the same gauge - the white slightly smaller. But at the plug end at least the white and red are commoned. Any idea why? The graphic on the PS just shows the normal 'sleeve and tip' connections.
