I would just like to know if it would be possible to fit and wire up rear seated entertainment headrests in my range rover sport hse 2006 (as it currently does Not have them, there currently the original just plain normal headrests) simply enough ? Ie once the REH headrests are inserted and the wires pushed down the through the headrests holes, is there or would there be and ALREADY FITTED HIDDEN power connectors inside the the back of the seat for the NEW TV HEADRESTS I want to fit too connect too ?? As I'm.not an electrician and so don't want to be adding or cutting any new wires as that's a job I can't do
