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
Lets see, no nudes and no phone numbers. Your probably good on the post. LOL
But to get any good info you will need to provide a bit more yourself. What are you working on? Are you starting with a factory harness? If so, what do you want to change?
