I used to skip labeling wires until a mix-up cost me half a day
I thought keeping track in my head was good enough for small jobs. A messed up panel from swapping two sensor lines made me start labeling every single wire now. Do you label as you go or at the end?
Totally get that, I mean it's not just for you but for whoever might work on it next. Idk, maybe it's a pain in the moment but it saves so much hassle later. You're basically leaving a clear trail for future you, and that's always a win.
