Not to be a Samrt-azz but do a Google search of Images " Race Car Wiring". There are a lot of pictures out there.

Wires & Pliers and Spaghetti Menders also have some good pics on their websites.

I'm with Leon on the ARC stuff, Looks good and is reasonable on the price.

There is Better out there but you'll pay dearly for it.

Do yourself a HUGE favor and make the install neat, clean and label your wires.
