BMW E61 Tailgate Wiring Repair

In this video I go through the tedious process of repairing the wiring leading to the tailgate. This is the number one most common issue if your key stops unlocking/locking the doors when you press the button or your rear glass won't open, or any of the lights on the back stop working. All BMWs from this era will at some point have this problem, even ones with a trunk.
You will need:
Torx 30 bit
Torx 20 bit
8mm socket
13mm socket
some wire
This is the wire I used:

wire strippers and cutters
some method of connecting wire like a solder and a soldering iron
electrical tape
heat shrinks insulators or alternative
plastic prying tool
patience & time
