As suggested . . . get the airplane built first . . .
or at least mostly built. Check out exemplar airplanes
at OSH, talk to the builders, join one or more Bearhawk
forums.
Find out what things make sense to assemble out
of the airplane. The peg board is used in production
environments to great advantage for cookie-cutter
airplanes. But know that most peg boards are
designed around a harness that was built up in the
airframe first then used as a model for duplication.
Further, the board may be 'adjusted' several times
before the installers offer to buy beers for the
folks on the wire balcony.
Do the page-per-system wirebook. Wire each system one
at a time . . . there are no 'complex' systems . . .
after you've completed a dozen or so pages of wiring
you find yourself all done.
There is VERY little wiring associated with radios
that is not concentrated in instrument panel area
and again, on a radio-by-radio basis . . . pretty
simple.
Your biggest single asset is a line of communications
with folks that have been-there-done-that. It's even
better if you can see what they've done by looking at
the airplane (osh again).
But I cannot recommend purchasing any whippy products
offered over the counter at OSH until your fellow builders
have given the thumbs up for return-on-investment.
Having been to osh perhaps 18 times, I can say that super-selling
over the counters and digging through the super-garage-sale
at the north end are problematic for the neophyte builder.
The biggest bargain I ever purchased out of the Fly Market
was a King KY-90, S/N 110 . . . probably built by hand in
Ed King's farmhouse factory south of Olathe, KS. I think
I paid $10 for it.
The various Lists and Forums on the 'net are your best
resources for data and advice. Your best resource for materials
may just turn out to be eBay . . .
Let's talk . . .

Not nit picking here . . . but read chapter 17 again.
There is no such thing as a 'safe' airplane, only low-risk
and lower-risk airplanes. All airplanes are dangerous as
hell in their ability to make your day very miserable.
What does 'reliable' mean . . . nothing ever breaks? Won't
happen. ASSUME that everything you bolt to your airplane
is going to break.
How will you KNOW that it has broken?
If in flight, how does failure influence likely
outcome of the flight?
Can the failure be pre-flight detected?
If loss of that feature raises your level of
discomfort to unacceptable levels (too much
risk) then what is your Plan-B for mitigating
that failure?
The lowest risk FLIGHT system is fabricated by a
builder who understands systems sifted for high
risk failure modes and flown by a pilot who is confident
in the builder's decisions for crafting a FAILURE
TOLERANT airplane.

I don't often offer my advice but I will on this one occasion since the ori
ginal post was from an admitted newbie.
Don't buy any major components (Avionics, Engines, radios, props, =C2-etc
.) until you are ready to use them.
I have found thru very expensive experience to make an ordered list of smal
l projects to be completed over a measured period of time.=C2- I then rev
iew that list, determine the parts (if any) that are required and order the
m at that time.=C2- I=C2-keep the time frame short for the list (1 mont
h at most) and delay any major purchases until I know that I can't work aro
und them.=C2- Make your decisions on what you are going to use and build
toward that but be flexible, so much is changing that you don't want to get
caught with a lot of expensive equipment you will never use.
My advice is free but the experience that it is based on was very, very exp
ensive.
