wiring diagram for the bcu. td5 interior lights

the last of my "to do" jobs is to sort out my interior lights as they have stopped coming on when the car is unlocked, I have found out that if I press on the thick loom in the pass foot well then they will sometimes work, so I was wondering if any one has a pin out diagram for the body control unit so I can start tracing the correct wires and doing some continuity tests,
thanks

Hi
if you remove the front passengers kick panel there are several plugs, cant remember which, but you will likely find some of the pins are corroded, or possibly plugs not seated fully.
if the corrosion is not too bad, just clean up with electrical contact cleaner and check for any leaks, which on mine was from base of windscreen.

Pin 9 of the third connector away from the end with the spike and rubber ring.

Connector C0662.
