Mistake on the 98 wiring diagram?

[His Dudeness]

I think the black is a ground going back to the ignitor. That black connects to the black directly below it in the alarm. So it's a ground when the side stand is up and the key is on. The blue is 12V coming from the light switch and going to the tail light. I don't know why you would connect the light switch 12V to the ignitor ground. Wouldn't that just short the light switch? I added a pic of the connection.
