Just to say I've not forgotten about this project. It becomes cheap tax (30 years old) next year so i will be picking up the theads soon. I did get another discovery 1 clock" (the one in this thread from ebay)but It doesn't work properly as the electrical wires connections have rusted through (you can see it in the pictures rust spots along the copper lines, and i did ask the seller but he said he hadn't noticed anything and it was fine , but its not , so Im going to have to get yet another and see what can be done. So I will be back if nothing else but to put up pictures of the completed project. Thanks again for your help.
I always get a laugh from people when i tell them that you have managed to instruct me how to wire in a disco 1 analogue clock into the disco 2 digital electrical system . When I turn the key all the warning lights come on and off again and check engine comes on and off , and i always marvel at how clever the ECU is to check the engine even when it is at the other side of the garage and not fitted into the chassis yet!!
