That wiring loom on the CRJ was a nightmare last week

Took me 6 hours to trace a bad pin on a cannon plug. The print said pin 22 but the actual wire was in slot 18. Someone at the regional line station must have swapped it during a quick fix. My lead just shrugged and said "that's what happens when you let the overnight guys touch avionics." I swear these short cuts are gonna cause a real issue one day. Has anyone else dealt with mis-pinned connectors on these legacy birds?

Oh man, I feel your pain. Last month I had a 737 that kept throwing a fuel quantity fault and after two days of chasing my tail I found pin 14 on the EICAS connector was actually a splice job hidden behind some tape. The original pin had snapped off and someone just shoved the wire into a different slot and hoped it would stay. The prints showed a standard pinout but the reality was just a mess of shortcuts from years of quick fixes. It's scary how many of these old airframes are held together with hope and bad wiring.

Check your grounds before diving into the wire bundles every time.

You find that a lot on the older planes, @anthony129?
