Mistake on the 98 wiring diagram?

[BBROWN1664]

If you look at the ignition in the 98 wiring diagram http://foc-u.co.uk/index.php?action=down...iew;down=8
The diagram shows a connection between the blue wire coming off the ignition and the black wire going between the alarm and the ignitor. Is that connection a mistake?

Looking at the diagram, I canot see a blue wire coming from the ignition. I can see a black wire that connects to the black wire to the igniter/alarm
