Builders in the experimental category will not be able to farm this work out as all the points for each category have been assigned to the builder to meet CASA's/ FAA 51% rule. See AC 21.29 Flying Legend Web Site Australia.
What is hiding in the cockpit shown below ?

The best place to start wiring is on paper, it's cheaper, more effective in the long run to have some idea of how you will approach the task on your aircraft. Trying to undertake wiring on the basis of "doing it in the fly" will get you there but will consume wire, crimps and add unnecessary time, weight and create a spaghetti bowl to tidy up.
Will there be errors in the any diagram created - "YES" - but any plan is better than no plan. This builder has tried the latter and learnt from the error..!

The Vertical Power article has some really useful tips and links. The information on Alternators is not applicable as the Rotax has a generator and if you chose the added a alternator it is covered in the Rotax manual. The Rotax manual ALWAYS is the final source of information and MUST be adhered to strictly. Do not digress unless you have the knowledge or under guidance for the particular application.
The FAA Wire Sizing Chart's are reproduced below.
In practical terms curve one [1] & three [3] are the most applicable to light aircraft but the chart in the Vertical Power's wiring notes is most useful for this type of aircraft. The wire sizes for the Rotax Engine are quoted in square mm and the conversion chart is useful to size the cable in the more common A.M.G.
