Hi Gordon, I have a wiring diagram but they are not coloured.
On the diagram it tells me that there is connection 2, 4 ,5 and earth.
On tag 2 a wire goes the safety stat. and this then the other side goes to 2 on the timer.
On tag 4 it goes to P3 on the front of the selector.
On tag 5 It goes to the other side of the cooling fan in the top.
Hope this helps. If you cannot trace then ring Extracare on 08457959722 and I am sure they can send or fax a copy of this diagram if you ask nicely.
All the best.
