We now need to look at modifying the car interior. In order to do this, clip together the interior base and flux capacitor back-board as shown.
The first modification required are two 3mm drilled holes in front of the two seats, where the two UV up-lighters will be positioned.
Four fibre optic strands are used to illuminate the flux capacitor. With the car backing fitted to the interior, use a 1mm drill to create holes as shown on the flux capacitor. A single 3mm hole is then also needed behind this back-board as shown, to allow the fibre strands to be routed from underneath the car.
