Central locking wiring help

[Mrcirrus]

Hi my MK6 2004 has broken all six black wires on the off side rear door central locking loom where they pass into the rear door. I’m loathed to fork out for a repacenment when I can solder them back. But which goes to which. They are coloured either side of the loom. Anybody got a wiring diagram? I carnt be the first person to have this problem, thanks

You don't really need the diagram if you've got a multimeter. Unplug the lock end and buzz each wire through from the door connector to the broken ends, then you know which stub is which. Easiest way to not lose track is to do them one at a time and stagger the joints so they're not all in one lump. Use proper flexible multi strand wire for the repair because that bit flexes every time the door opens, which is why they broke in the first place. Solder and heatshrink each one and leave a bit of slack through the gaiter.
