Every connector on the car will have what is called a "pinout" what this allows you to see is what every pin on a connector does.. Whether it's data, live power or something else.. Sometimes you'll be missing a few pins from a connector (usually when your car wasn't built with a specific feature and you're trying to add it) so with a pinout you can see what you have and what you need to have (or add) to get something working
