What Is The Black/yellow Cable For In Tailgate Loom

[darren]

Hi there, i have been checking cables in tailgate and doors, and in the tailgate loom, there is a black and yellow cable that has broken. Does anyone know what this is for as I have no idea. There is a towbar fitted, so dont know if it's for that. Also, does anyone know what colour cable is central locking. Many thanks.

First question is what's not working? I went for four years using key to open rear door to later find broken wires in loom, now all lock, the car was like that when I bought her so I thought that was the norm, it was only after looking on here when rear wiper stopped working I looked in rubber gator and found a right mess, to fix did a visit to local scrap yard and cut out a long section of wire in rear door pillar, cut out crap and joined in pillar and under trim in rear door, leaving plenty to flex in rubber gator, it's easy doing it this way as colour cables stay the same.
