Why run a new wire ? If you've got a red/orange or red/yellow or similar red running to the door that also contains a yellow wire and a white wire, then this is also fed from fuse 10 and will feed the mirrors and central locking. Just check that this wire has permanent 12V to it. If so, then just tape up the loose single red wire you've got.
