Wiring loom issues

[Baykiz]

Hi, I'm new here as u have just bought a mk2 focus(2007) saloon.  My number plate lights are not working. I checked the loom going into the boot and discovered that the wires have broken. There are 7 black wires in total and 3 are broken. Would anyone have a wiring diagram to show which wire goes where as the wires are all the same size and not color coded?  Thanks in advance.

If you go to the Focus part of the forum there is a pinned topic named Mk2.0/2.5 Wiring Schematics (or something very similar)
