I was crimping RJ31X plugs wrong for years until a customer pointed it out

I always thought the tab went down, but this guy in a big house in Scottsdale showed me his old system and the plug was flipped. Now I check the wiring diagram every time. Anyone else have a basic thing they messed up for way too long?

Scottsdale mansions will humble you quick. I kept mixing up the A and B standards on keystone jacks for a solid year. The diagram is your only friend.

Oh man, @paul_owens25, that hits home. My buddy wired up a whole home office in one of those places. He was so proud until the client called saying no internet worked in the east wing. Turns out he used the A standard on one end of the runs and B on the other. He had to re-punch every single jack. The diagram was face-down under his ladder the whole time.

That reminds me of a job where the client wanted every room color coded. We spent hours matching keystones to paint swatches, then the electrician went and painted over all the labels. Had to tone out every single cable again.
