Sliding Door Electrics

[t1tmt]

I need to get power into the sliding doors of my 51plate berlingo. What I need are the electrical contacts that fit to the door and door frame completing the circuit such as those on the central locking model. If nobody has any, then maybe a part number would be good as the dealer couldnt help me as mine isnt fitted with them as standard so couldnt look them up.
