Hot take: Older aircraft pinout diagrams vs. modern digital schematics - which one do you trust more?

I was tracing a power issue on a 1990s King Air last week and the old paper pinout showed pin 7 as ground, but the digital revision says it's a data line. Tbh I've seen digital updates that were supposedly corrected by the manufacturer actually introduce more errors than the originals. Ngl, I lean toward the paper ones unless I can verify three different sources. Which camp are you in when the two conflict?

Whoa, hold up. Pin 7 is ground on one and a data line on the other? That's a straight-up nightmare waiting to happen. I'd be triple-checking everything before I even breathed on that harness. Honestly, that kind of mistake could fry a whole board or worse. I'm with you, paper all the way until I've got three sources screaming the same thing.

@reese_hayes71 Same pattern everywhere. Trust paper over digital. Less room for silent screwups.

Have I ever told you about the time I traced a pinout for three hours only to find out I was reading the connector upside down? Yeah, that was a fun day. I swear I learn best by making every possible mistake at least once, just to be thorough. Your mileage may vary of course, but I've found that paper schematics and a magnifying glass are the only things keeping me from turning perfectly good hardware into expensive smoke. Triple checking feels like overkill until the alternative is a dead board and a lot of cussing.
