I have done lots of research and looked at wiring diagrams and I didn’t believe this should be as complicated as it seems to be. Other than the below diagram which I have followed I cannot find anything that gives a simple which wire goes on which terminal. And unfortunately the below does not quite match what I have.

I dont want to be rude but I do not want advice to follow the wiring diagrams. I have studied them and they do not help when lined up against the actual physical switch and the colours given do not match the colours I have. I am aware what should happen at each stage of ignition and what should be live when. Unfortunalty I currently do not have power as I have not finished the engine bay fuse box. So other than testing continuity I cannot test other things in the loom.

I have followed this diagram for the ignition switch but I am unsure if I have plugged it in correctly.

I have four wires (new 300tdi main wiring loom), thick white, a thin white, a brown and a thin orange/white but not sure I have connected up correctly. My starter solenoid wire on the engine bay side of the bulkhead loom is brown/red, which does not match the wiring diagrams I have seen! I currently have it connected as follows
  1. Thin white
  2. brown
  3. thick white
  4. blank
  5. white/orange
Is this correct? I currently have no power as have not finished connecting the engine bay fuse box so cannot run power to test!

I will try and get back to the vehicle tomorrow to check if I have continuity between the thin white and the starter solenoid wire on the engine bay side. Other than this is there anything else I can do to try and verify I have connected it up correctly that is not more studying of the wiring diagram!
