Take the window ledge section and with the back of it facing down, take a
White 15cm Bit Light
and place it (facing down) flat against the bottom of the
ledge in the centre. While holding the cable in place with your thumb/finger,
reconnect this section to the front of the building ensuring the Bit Light cable
is in between studs. If you look from underneath you should be able to see the
Bit Light peaking out underneath the window ledge.
Reconnect the light tan plate over the top followed by the window section and
surrounding pieces we disconnected earlier.
