Anyone know which wire does what?

Postby scottflit » Mon May 21, 2018 8:49 pm

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.

It's the single wire which attaches next to the bulb itself, you can see the bus bar that the wire connector attaches to at the end of the red wire in this picture

The double plug at the end contains the switched earths :)
