Hi guys, I've got a bluetooth hands free installed in my car, and I've just bought a holder for my phone which came with a plug-in-the-ciggy-lighter charger cable. Because of the position of the lighter socket in the Cab, this is going to look a tad unsightly. So, I've cracked open the casing of the charger plug and whipped out the electronics, I intend to put these into a small box (or probably just end up wrapping them in electrical tape!) then pop this behind the air-con control unit. So, I need to tap 12V from somewhere behind the aircon/radio, there must be at least 2 there! Can someone help me identify which wires are the ones I'm looking for? Cheers.
