Mark, the electrics attach to the windscreen through the frame at the bottom, right in the centre. On Richards picture the blue and black wire are from the screen and are connected to different colours with bullet connectors in the loom. the screen wires should be routed through holes made in the lower screen seal. They then track under the dash rubber bumper , covered in trim leather, and through a hole in the front scuttle where they then enter the below scuttle area. Now unfortunately if any water enters the lower screen seal at any point, usually from the outer ends of the screen seal, it can track along the inside and enter the car below the scuttle through the screen wire hole.... this is something you really do not want as the electrics are very very vulnerable to damage from water and the PCB incorporated in the cluster is fragile and now unavailable!
If you search my posts I have written a scree on replacing the lower screen seal which will help you see it more clearly should you need to go to that extent PM me an email address and I can send you some clarifying pictures of how I achieved this. Check also the washer hoses and connectors are patent as water can splash everywhere if not and if you have black tubing and connectors change the whole lot out while you are there as these are absolute rubbish! You will see again on Richard's pic the cleat tube replacement. Lastly it's not impossible for the heater rad to leak either at a hose connection or from a matrix fault.. smell the area or water drops to identify if its coolant.
