Strange one this…

I’m fixing a couple of damaged wires that go through the bulkhead.

The wires in question are taped together with the main big fat live cable that goes to the fuse box.

The wires taped to it are
Yellow/green
Red/?
Black/Green
Black/Green
Brown
Brown

Now, of course Sod’s law dictates the ones that were split were bother black/green and both brown.

My question is I’ve got a 50% chance of getting them the same way round does anyone know what they are and if it matters if the wrong black green is connected to the other?

Brown is normally earth, so shouldn't be a problem if swopped.

No idea what the Black Green is.

What model / year is the car ?
If it's as your signature 2007 MY, there appear to be lots of uses for Black / Green, but I can't spot on the diagrams I have it used in combination with those other colours.
Are the Black / Green cables fairly thick ? If yes, might be Front screen wiper blade heater or washer jet heaters (all 2.5mm2 cable) . Its a reaaly common colour for lots of different sensors if 0.5mm2 cable Paul,
