Installing Roof Mount DVD Player in WH Statesman

[VQXTC]

Hi there all, It has been a little while since i installed dvd players onto car roofs, and I am running a blank but the question i am asking is how to hook up the built in lights in the dvd player to the existing wires which come from the factory interior light...... ?

I know in the WH Statesman the body control module controls the factory light ... does that sound right??

cheers

Simon
