Hi Guys.. does the wiring loom carry all the cables?? for example.. I have a Ghia MK111 and the back quarter windows do not open due to this being an extra. I want to buy the motors and switches but will the wiring be in the existing loom???? I have tried looking but the loom seems to be very tight in the over head interior, it would all have to come down to check it. can someone/ anyone let me know..please many thanks Tony
