Intro & Newbie question

Hello,
My name is Nick and I'm a manager of a small auto repair shop in California.

I just got my Pico 4423 and please excuse my newbie question: I've been playing with the system and have got my parade of the secondary ignition. I haven't, however, figured out how to determine which is the #1 cylinder. Could someone please point out how this is done?

Thanks,
Nick
