T6 - load-area lights

[Campdavid]

This has been asked many times and I have searched, but cant find a definitive answer. I'm replacing the two load area lights as part of my conversion. I just want the lights to come on when a door is opened and go off on a timer.

The wires are:
Red
Brown
Red/Brown

Which is the permanent live feed and which is the switched negative on a timer when the door is opened? (or reversed if its permanent negative and switched live) I have got a multimeter, but its really awkward to prod around when bent double!

black/red +12v timed from the BCM
Brown/red -12v switched by the doors

Thank you for replying quickly. Sorry to be thick, but I haven't got a black wire.

I've got:

Red
Brown
Red/Brown

Which two do I connect to the bulb?

The red is permanently live, so presumably either [Brown] or [red/brown] is switched negative by the door and on the BCM timer? Do you know which?

Thank you. That worked. I need to go to Specsavers, because I couldn't see the red (with the thin black) at first. I just thought it was solid red!
