Found out a DC-9 has over 3 miles of wiring inside it

I was helping a buddy pull panels on an old DC-9 last weekend at the hangar in Tulsa. We got to talking about how complex these birds are, and he just casually drops that there's around 18,000 feet of wiring in the fuselage. That blew my mind, considering it's not even a widebody. I checked the maintenance manual later and yeah, the number checks out for that specific model. Makes you think about how much time goes into tracing a single short circuit on those things. Anyone else run into a stat like that on a plane that just surprised you?

How many hours did that short trace take you?

And did you figure that out on your own or have a mentor walk you through it?
