PSA: I crimped 200 pins with the wrong die and only caught it on a night shift in El Paso
Three months back I was knocking out a big harness rework and using the die that came with the ratchet because it fit the pin, so I figured it was fine. About 200 crimps in I pulled on a lead and the wire slid right out of the barrel, and I looked at the cross section under a loupe in El Paso and saw the insulation wasn't even getting touched. Turned out I needed the B die for that pin gauge and I'd been running the A die since I opened the kit. Gave the whole harness a tug test and had to redo 40 of them at 2 in the morning. Anybody got a favorite way to mark their crimpers so this doesn't happen, or am I the only one who trusted the label on the case?

A few years ago I would've told you just read the case and move on, no need to get fancy. Then I mixed up my A and B dies on a batch of Deutsch pins and spent a whole Saturday fixing connectors that passed a visual but failed a pull test. Now I keep the dies taped to their own ratchet, and I painted a red stripe on the B frame with a Sharpie. Sounds dumb until you're half asleep at 2am and grabbing whatever's closest. You're not the only one who trusted the label.
