Battery Disconnect

The factory insists that the battery on the car has to be disconnected while the vehicle is being towed.  I didn't want to have to mess with taking the wire off and on the battery every time I pulled the car so I installed a disconnect switch in the engine compartment.  That's it in the lower middle of the picture.  For only a hundred euros and two days of work I can now turn the battery juice on and off at will.
     Of course, all of the downsides to unhooking the battery still apply.
