See what colour wire has been taped up and find it in the engine bay, then untape the wire at dash end and you should be able to see which terminal it goes onto in the multi plug that plugs into the clocks, reconnect and job done.
If it comes to it just run a seperate wire from sender to clocks, PM me if still stuck and I'll find wire colour for you at sender and terminal postion at clock end.
