Ok, searched for posts, checked the fuses, checked the bulbs, looked for the reverse light switch on the gear box, but cant seem to find it.
I have no reverse lights but i definately used to. I think it is since this wire started hanging down, as nothing else seems to be affected.

Would like to get this wire going to where it belongs, before i try anything else. does anyone know where theirs go, if they have them? In the picture there are two wires. one is red, one is black, so i assumed they go to the same place. however connecting them to the same fuse did nothing.
can anyone shed some light on this ? Its a 1984 8v gti.
Thanks
