1981 K15 Ignition Switch Wiring

[81SierraGrande]

Long story short, I have installed a new wiring harness in my truck, the ignition switch wiring I used was from the new wiring harness diagram (attached). Is this correct? It was a universal wiring harness with gm plugs, I am not sure if this is correct and can not find a good diagram to check. It also calls for the grounds to be during crank only and I have no idea what that means. I thought a ground was a ground? I have a short running through the system somewhere and this is one of the last things I know to check before I start pulling hair, cussing, etc.
