Land Rover Repair: Disco 1 manual sunroof leak, drain tubes, sunroof assembly

Question
Rear sunroof on 1998 300TDI leaks water into roof lining. I understand there are drain tubes, but I can't find them.
Can you please advise the location of both the inlet and outlet of these drains?

Answer
The drain tubes exit the sunroof assembly at the left and right front corners, going sideways to the left and right.

1.   Ensure sunroof is in normally closed position.

2.   Disconnect battery negative lead.

3.   Remove headlining.   See  headlining.

4.   Disconnect electric motor wiring plug.   See sunroof electric motors.

5.   Remove screws and detach electric motor from clamping frame.

6.   Disconnect drain tubes from each side of clamping frame.

7.   Remove 13 fixings and remove clamping frame from upper frame.

You don't have to do this to clean the drains but it points out that the drains are kind of buried and hard to see.  Look in the corners, facing the sides, in front.
