Hi.
Thanks for all your replies.
the original chassis was so rotted out it was beyond saving.
As far as the injection system that I have all I know is that is from a 1995 discovery 3.9. I bought the car complete as a donor.
the ecu does have some code numbers on it and I will have a look at it at the weekend to try and get more information.
At least with the wiring diagram and can now at least see the ignition switching.
what I’m not sure of is the wiring from the auto gearbox must connect back to the ecu in order to stop the engine starting if it is not in park or neutral, but that part of the loom goes back to another box.
appreciate all your help.
