Schematic Print to OS correlation?

[Madmax]

I have always had this nagging question in the back of my mind, Is there a difference in (411) OS wiring strategies? Well I now have 2 different wiring strategies in my possession, both in an excel format and both in schematic form. First issue is injectors #2 & #3 are swapped from one set to the other "I'll dig into this more tonight. I am wondering if I have a bad pin out and drawing, or is there something to OS specific diagrams and pin outs? my OS is 12212156, if someone has a known good drawing / pin out for this OS please link it?

and is there a difference in OS and wiring strategies?

P.S. I'm guessing that I'm looking at more of a year specific issue???

One more quick question, for clarification. Ive been told to use (RED 26 Ign control #1)to run with
a Vortec distributor and single coil, is this correct?

P.S. I am running a 4x crank signal. I am thinking about going 24x and CNP at some point. Maybe I should concider it now?
