1954 NAA (Jubilee) 12v wiring from scratch step by step Help

Hello, I have a 54 naa that the wiring harness has been ripped out completely due to it being rotten and shorting out at some point and previous owner was in the process of converting it 12v and never got around to it and gave me the kit that comes with alternator and wiring ect but the directions are very cryptic to me and make no sense, I came here and looked at the conversion chart for 1 wire alternator side distributor 8n/9n and Jubilee and it is slightly different then the diagram that came with the kit mostly with differences how wires are run to and from ampmeter and terminal block are different but i was told the best way to follow was the diagram Here.
The problem is i am not a electrician and sort of dumb where wiring is concerned, and the wires that came in kit have totally different colors then the ones in diagram here and it would be nice if some one could walk me thru wire by wire step by step on how to rewire this tractor just looking at diagram is greek to me without some one i can follow that knows what they are doing. Also this tractor has a aftermarket 2 wire push button start added and the original 1 wire grounded push button is cut out and i am not sure how that would be wired up in this conversion either, It had 1 wire to solenoid and the other right to battery before when it was 6 volt.


I'd appreciate any help I am going by the diagram below i am pretty sure it is the correct one i need to use even though it says 53 jubilee mine is a 54 but i'm sure it is the same.

This is more of a picture, so maybe it will help you. You will need to ignore or re-map the colors to what you have, since your harness is not original. First is as from factory. Second is marked up for 1-wire alternator.
