Hi guys.
I'm in the process of wiring some led work lights into the back of my van, and wanting to take a permanent 12v supply from the light above my head in the cab. The only problem is, I can't work out which of the wires is the permanent live feed in the fitting. Am guessing the single wire is the -ve, but which wire in the 3way plug is the permanent +ve? My instinct is its the middle one, but I don't want to break into it if it's the wrong one...
I wish I could photograph the fitting to show you, but my cameras fubar'd on my phone.
