Wiring diagrams 1967 3.4

Hi friends…I have problems with the lights on my jaguar. .but I do not have the electrical diagram to look at the route of the wires … where can I get a diagram with details ???thanks for all

If you have owners manual you will find electric schematics on next to the last page. Or try to find a copy of Haynes workshop manual.

Also it will adhere to BS-AU7.
Google that and you get all the wiring colours which is incredibly helpful.
