Over the years I'm surprised at how many little additions and changes
I've made. They would have been easier if I'd been more careful about
marking both ends of every wire. Some of my changes were not as well
documented as the original build which didn't help. Using mostly white
wire because it was cheaper and easily available didn't help. Obviously
access to wiring will become more difficult later so the little things
will help later on. Using lacing instead of tie wraps worked well for me.

Bob,
Here's the schematic, and late breaking...the ballast mfgr engineer informed me
that the max inrush for the ballast is 101 A. Combined with the Pwr Supply's
40A inrush, rough duty for a 5A switch.
Thanks for looking at this,
John

Art,
Here's my tuppence worth ...
Implement your harness build with the idea I mind that you're going to have to
get into it again at a later date and when you're a bit older than you are now...
- service loops so you can remove items for maintenance
- make things a "modular" as you can without adding excessive complexity
-- if you build it so that all or significant parts can be removed without
a big hassle it makes it easier later to modify or repair
- it's very helpful to have the panel on the bench, with the trays and components
installed ... wire it from the back of the panel on the bench, power and
test on the bench and then install in the airplane.
- color code where possible and within reasonable budget constraints ( red=power,
black=ground, yellow=lighting, etc)
- (use the same color wires on multi-conductor cables to do the same job throughout
... if you use the blue striped wire as an audio low on one headphone jack,
do it for all of them)
- label wires. I use a Bee3+ heat shrink printer, but white heat shrink and a
sharpie would be cheaper and just as effective.
- build a neat harness. Plan ahead as much as possible. It's a 3-d puzzle. Think
about flight control movement and possible interference issues. I start with
the fattest bunch first (com/nav audio lines), plan the route of the first
one and then add in one at a time, sizing to fit the route for each. Then go with
the next fattest bunch. I use cheap zip ties as temporary stays and then lace
up when done and remove the zip ties (carefully)
- where you use connectors to join harnesses, build it so it's impossible to
hook the wrong ones together (if you have three sets of 9-pin mini molex connectors,
it's too easy to confuse em)
- offset shield ties, soldered junctions, etc at the point of entry into the
connector backshells so they don't all wind up at the same place in the wire bundle,
making an unwieldy lump.

Over time, I found the text made with fine pt Sharpie on white heat shrink fades/runs.
Wish I had stayed with my original method of inkjet printed on white paper
then cut into strips to be inserted inside clear heat shrink. They are crisp
and legible, years later.
Tag your circuits with masking tape/Sharpie. Precut heat shrink to slide as many
as you need on a wire, and pick a time just to insert labels and shrink the
covers. Goes pretty quick that way.
Use Red for power, Black for ground. Additional color coding consistency. Try to
keep it simple and use your wirebook to denote deviations.

I find it helpful to run all the serial wires into one side of a single
connector, then jumper as necessary with the other side of the connector.
Put the main end of it someplace where you can pull it out from under the
panel and work on it in your lap. My experience is that there are always
things that want another flavor of serial data, and it makes it easy to
distribute. I've used 100-pin CPC connectors in the past.
