This is a 3 page wiring schematic for the Mk2 Saloons and early 71 Mk3 Saloons.  Although the print is small (which you can enlarge yourself), it is laid out in the shape of the vehicle.  And this is the last and only diagram Jensen did this way. (wonder why?) The rest look like an intricate corn maze! These copies are 11 inch by 17 inch.
