That talk with a retired A&P about wire labeling

Last month at the FBO in Wichita, I was bitching about how long it takes to trace harnesses on old King radios. An older A&P who was just hanging around sipping coffee said 'you're wasting time, kid. You should be labeling every wire as you pull it, not after.' He showed me his system with a simple Brother labeler and it just... clicked. I'd always focused on the repair itself, not the documentation side. Has anyone else found a labeling method that actually sticks long term?

See, I have to push back a little here. Labeling as you pull sounds great until you're working in a tight spot where the labeler is on the bench and you're elbow deep in a tray. In practice, I found that stopping every two minutes to fire off a label breaks my rhythm and I end up rushing the actual removal, which is where you really mess something up. Instead, I take a quick photo with my phone of the wire bundle before I touch anything, then I hand-draw a rough map on a scrap piece of cardboard with a sharpie. It takes maybe a minute total and covers everything, even the weird ground straps people forget about. Labels are nice for the final install, but for the tear-down phase, a photo and a sketch has never let me down.

Oh man, that 'you should be labeling as you pull it' line hit me HARD. I had the SAME wake-up call a few years ago with a crusty old avionics guy who basically said the same thing. Now I keep a Dymo labeler in my bag and I label every damn wire the second it comes loose. It feels stupid at first but saves SO much time when you're putting it all back together three days later.
