electrical advice

I am going to be starting the wiring in my 74 dart, It is going to be a track only car. Battery located in trunk with shut off safety switch. I am not using any of the OEM harnesses I can figure out how to wire most items to the switches but am confused about is from the kill switch. Does it feed the fuse panel directly? Do I need relays? I am running a power switch, start button, electric fan, electric fuel pump, electric water pump, head/tail/brake/instrument lights. If someone out there has either some directional advice or a link to purchase these instructions that would work too. I can do it I just need guidance.

Thank you.
