S13 wiring questions

[KoukiMonsta]

Ok guys I'm going to wire up the car, basically 'from scratch'. It won't be a daily so there's minimal electronics and accessories etc. but there's still a few areas that I don't understand, any insight would be appreciated. Yes I do know the Fsm shows 'everything' but I plan to change a good bit of this for simplification reasons. Such as ditching pop up headlights. And running seperate switches for 'acc' 'ign' and start

I will be running a blue sea 12 fuse panel.

What can be combined into the same fuse for power?
- one fuse for each headlight ( as a precaution for not loosing both)
- one for all rear lights? (Brake, tail, tag, reverse) or do I need to seperate?

What needs a relay? Fuel pump, e fans, ign, headlights, ecu, coil packs? Other than that things should draw small current correct? Enough that a switch can handle, such as brake and reverse lights.

Circuit breaker or large fuse at the battery?

Last is the switch on the gas pedal (do I need it? What's it for? Tells the ecu WOT? Necessary in my sr swap?) and brake pedal has 2 switches, brake lights and?

Thank you to anyone who feels I am not capable of this. I have no fear in my ability to learn, quite quickly at that. I would be very appreciative of any helpful info on my questions.
