departing IFR from a non-towered airport that does not have a
remote communication frequency.

That's what I did - no issues so far.

I was thinking about coating my bus bars with heat shrink and just cutting
away where I wanted to tie in

This is not done in light aircraft. Seldom done
in the larger airplanes. I've often hypothesized
a teachable moment by offering anyone their choice
of tools to crawl under the panel of a light
airplane and then pry, bend, pound or twist on
any part of the airplane in an attempt ground fault
a bus bar.
As an example, here's the back side of a breaker
panel in a Bonanza:

Bus structures in other light aircraft are similarly
'exposed'. On the forward side of the firewall we find
this:

Lots of potential for arcs and sparks . . . assuming
that anything under the cowl is so poorly secured
as to become a risk.
While cosmetically pleasing, the dressing of bus
bars doesn't reduce risks but it does distract you
from what is probably more useful expenditure of
$time$ on your project.

Of interest may be a new yahoo group for those using Seattle Avionics
"Voyager" flight software just formed this week by a Garmin GNS480
user that also uses Voyager.

SA has both subscription based and free products, and customer
support from SA monitors the group and has replied to questions.

Thanks Bob,As I mentioned, it'll be a while before I can get back to work on the
Velocity, but when I do, I'll report whether I decide to maintain the center-tap
scheme or not and how well it works if I do.

Very good! Hope your project doesn't
have to languish too long!
