The "wiring diagrams" supplied with Europa, Kitfox, Pulsar, et. als.
are barely worthy of the name. Take a look at the service manual
for a Beech, Piper or Cessna airplane and note the page per system
approach to documenting how the wires go into an airplane. Only
Mooney (bless their stubborn hearts) torment mechanics with single
sheet, wall sized drawings of the whole airplane.

There are two main concerns for system development . . . mechanical and
elecrical. Elecrical issues go to circuit function, failure modes
analysis and parts count reduction. Mechanical issues deal with
attachement, support, double insulation, protection through firewalls,
interference with controls, etc. Many builders try to lump the two
tasks into one. I suggest that a page/per/system wirebook be developed
first to define equipment to be used, wire and fuse or breaker sizes,
connectors, splices, terminals, where to get grounded, etc.
When that's done, you can easily switch gears of thought and deal
with the mechanical issues as you bolt the hardware into the
airplane. If you've done a good job with the first task, the second
will be easier.
