Guide to electronics connectors and wiring techniques?

Anyone know of a good (preferably free) guide to electrical connectors and wiring? Not necessarily about soldering…

Thanks! :sorcerer:

You tried google, youtube and the likes ??

Edit: also the MIDIbox wiki might hold some goods - http://www.midibox.org/dokuwiki/

Yeah thanks I’ve tried google and the wiki… no luck.
