Main wiring harness from scrath... a few questions

[unfrgivn]

Quick Background
-------------------------
Hey guys, my car is an s13 with a redtop SR. I am very knowledgeable about 240's and engines (not some stupid kid with his first car). I have had this car for about 3 years (I swapped the engine about 2 years ago). This is a recently gutted track car, primarily for running track events up at Summit Point in WVA and occasionsal solo 2. It will see little to no street time, but I want to wire up signals, headlights, and stuff to pass inspection because I don't have a trailer 100% of the time to get the car to the track.

I know a decent amount about electronics and wiring in general, but haven't done much with car electrical systems, so this will be fun.

Questions Begin
-------------------------
Instead of the stock system where you have several different stages of powered devices CONSTANT 12v, ACC, IGN, START... I plan on having a master kill switch off the battery which then gives power to a momentary switch and a relay to power the starter solenoid, as well as power to a main fuse block which runs all the circuits for headlamps, brake lights, wipers, signals, ecu, gauges, etc...

1. Charging System: If I ground the alternator to the engine and run the other large bolt to +12v on the battery through a 100A fuse is that good enough, to charge the battery? Do I need to worry about the 2-wire plug if everything is just runing off the battery? I don't care about the charging light or anything, but if I need it then I can just wire up an incandescent light at the end of the white/red wire and what do i do with the white wire that normally went to the driver's kick panel fuse box? Does the SR alternator need a signal to start charging like some GM ones I've worked on?

2. ECU Power: Since I have no main engine harness anymore and the plugs for ECU power over by the battery tray are gone, I need to re-think this. I've looked at the FSM many times, but I get very lost in the huge mass of stuff that I'm no longer using. I assume ECU-Backup power is a constant 12v for when the car is off so the ECU doesn't loose anything stored in memory, Then there are 2 large power wires which can just be on when my master kill switch is on, and the last wire is the orange (ignition start wire) that plugs into the ecu along with the speedo/tach/consult plug that goes over to the driver's side. Is this wire also on when ignition is on or what? Does it normally get power from the alternator at the fuse box and can therefore just get power as well when my ignition kill switch is on?

3. Headlights: Once again I have read the FSM EL section so many times my head hurts, because some of the wiring diagrams are crazy with all the different options, high-beams, running ligths, headlights, motors, dimmer, etc... I want to run a simple switch that pops up the motors and turn the lights on, lowers the motors and kills the lights when off. I could use a DPST switch and hook up a timed-relays to each pole for sending the popup motors a 2-second singal because when constant power is applied to the motors they start to short after they fully open/close. I know stock there is a timer box that controls this, but I think using a timed relay will work just the same. There will be a 3rd relay that powers the lights off the same pole as the lights up relay. I am sorry this is so confusing, because I am very confused myself. Does what I'm saying make any sense at all or has anyone created a custom headlight wiring harness without the use of the stock timer assembly or stock headlamp relays?

I have everything laid out on paper and it's starting to make sense, but any insight into the above 3 systems would be greatly appreciated!
