Favorite electrical system design

It’s time for me to start thinking about what electrical system I’m going to build into my 71 project.
Since it came with nothing but the original Lucas alternator, I have the luxury of building something nice (but not overkill).
I have some ideas about what I might do but thought I’d ask people here that have already been through this:
What electrical system would you build into a 750? Change to negative ground? 3 phase alternator? Build my own wire harness? Build a fuse box? Lots of options. Would appreciate some practical advice.
+Has anyone a schematic for a negative ground system with electronic ignition?
Thanks All

Heres my negative earth, boyer powerbox and ignition rewire. very low wire count to rewire it this way.

I saw that post and saved the diagram. Plan to use Pazon. Thanks Old Bloke.

NICE! Thanks Old Bloke. That helps me get started.

Do ya want, looks, simplistic wiring, or best function for lights and horn?
Hard to beat the Lucas look of factory loom, even with its half a shoe box full of unless dead ends and double back red wire loops for police sierns, radio and emergency lights.
You seen Bloke nice straight forward almost full function graphic but even simpler to search up, ugh, Chopper wiring outlines, though traditionally one color wires : )
For best function relay the lights, which if clever, with non factory wires, can be done with just two, but otherwise three to use factory loom, at for me.
Ignition only draws like 5 watts/3 amps so direct wire off main fused power lead does fine.
Horn don't get held long so no electric hazard reason to relay it but sure does get brighter like the headlamp when it is, but its still a muffled beep even so.
Winkers are a big joke of false security and I'd much rather have Bright running lights at all corners than signals. You head lamp, brake light and position and speed in road should reveal your intentions, so if those are missed do ya really think the signals would be more noticed? I flag my have with a finger pointing my intentions, tipping it in same rate as most winkers do, then grab bars with both hands to do the deed.
There are some neat off the shelf kits you just plug wires in and out to centerlize and compact terminations, some with LED's fuse alerts and such.
I have a custom internal relayed and breakers loom for Peel and decided to wrap in gift package ribbon or other cloth ribbon. One its for a girl and two its cheap and easy to replace or change to match Peel's changing moods. Kickstart Peel even has a use for the heavy duty electric starter circuit not to go to waste.

I think you made any hidden security system that will help the people to secure their bike from thieves.Because most of the thieves know that how to disable the alarm and other tracking system that the people are purchasing from any security company.
