Hi Jonny,
Do you know if its much hassle to swap it all over from a donor car? What all would it involve?

If I've read this right you'll want to take the loom from the donor car and swap it over, then on the ignition wiring you'll have a black transponder that fits around the ignition barrel. Take this off of your loom and attach it to the new one otherwise you won't get far. You can test the loom without having to wire the whole thing in properly - just attach the ignition, the dials and the earth by the accelerator pedal and you should be able to fire her up.
