Welcome to Chief Delphi SkiRacer!
My first suggestion to you would be to
read as much as you can within Chief Delphi’s Electrical Forum
One helpful thread that comes to my mind is this:
Neat & Organised Electric Wiring
Also check out the Whitepaper section of Chief Delphi, where you can download a lot of useful information about many different topics.
These are some whitepapers which may be helpful to you:
Electrical Tips Handout
Robot Battery and Electrical System Guide
Good luck!
