The second pic looks real familiar.
This is the sort of work that I quite regularly are sent in to tidy up or fault-find.
The only neater stuff that I work with is the stuff that I have installed myself and even then I've never had a call-back to see my work again!.
It's quite true though, you open a panel up and see nice neat wiring, labelled terminals, etc and you think, well there can't be much wrong here.
Open up a panel with a mess in it and you feel like running away.
