Hello, I currently own a Ford Galaxy GHIA 2003 and have gone through the excellent topics surrounding window problems. I have a snapped brown, white and I think green/red cable which is causing the windows not to function correctly. I want to extend the cable to avoid this issue in the future but do not know which amp/thickness cable to get. Halfords sell brown 27amp cable which looks the same thickness, also 5/17/27 amp other cables in various colours. I would really appreciate it if somebody could tell me which cable I should buy as I don't want to blow anything. Many thanks in advance!
