That huge number of wires in one bundle shocked me

I was reading a teardown of a 737NG avionics bay last night. Found out a single wing-to-fuselage connector can have over 200 pins. That's just for one bundle on one side of the plane. My head spun thinking about tracing a fault through all that. Has anyone here actually had to pin-out a bundle that thick on a job?

Oh man, that is just wild to think about. I mean, 200 pins for one connector on a single wing bundle sounds insane to me. Idk how anyone even starts tracing a fault in something that dense without losing their mind. I bet the wiring diagrams for those are basically a nightmare of lines and numbers.

My brain short circuits just looking at the pictures.
