Front interior light wiring diagram

Hello, my first post!  I have recently just purchased a Zafira B 1.8 SRI.  I am looking to install a flip down dvd player to replace the centre dome light.  I can see that the wires to the centre dome light will not take the load required for the DVD as it is a flat ribbon so I want to run the wires through the head lining to the front interior light cluster.  Can someone help me with a wiring diagram?  My DVD player has red/black live and gnd wires plus blue for door control and yellow for acc ignition wire.
