Question about the old way of checking continuity on those multi-pin cannon plugs

I used to spend forever with a multimeter and a pinout sheet, checking each wire one by one. Then a guy at the MRO in Mobile showed me his homemade breakout box with LED indicators for every circuit. Built one myself for about 80 bucks in parts, and now a 56-pin connector takes 2 minutes instead of 20. What's your go-to method for a quick continuity check on a big harness?

Ever try using a cheap audio probe to listen for the click instead of looking for a light?
