School me on wiring

Not sure if this kind of post is allowed, but here it goes. I have very very basic understanding when it comes to wiring and such. Ive wired a LED headlight to a go kart with a switch and a small battery, thats about it. Pretty soon i'll need to get my headlights, tailights, ignition, fuel pump, etc wired up and i have absolutely no idea what im doing. So if you guys have any tips or tricks for a beginner it would be greatly appreciated. I realize that i need to research elsewhere to figure it out completely but i thought this would be a good place to start. Thanks in advance
