You don't even need the new +12V power wire, the factory pink wire is thick enough and goes straight from fuse block. It's just the ground which is missing, except the driver door where the thick black wire goes to the switches. In driver door you have everything and on relatively short & high gauge wires. Unless you have the issue with existing ground I'd not bother with pulling another wire.
