How to wire up a boot light?

A few days ago I posted a topic about the light-unit I installed in the boot, see this topic. I used the wiring of the interior light to power the light in the boot. The wires of the interior light go to the driverside of the car. So to get there you have to remove the panel. The panel has only two clicks, see the images below. I hooked up the extra wire of the boot light and I taped it tight together.

The interior light uses 3 wires: a red wire, a blue wire and a black/white wire.
You need the blue wire and the black/white wire for the light in the boot.
