George,
Excellent work on the bridge and piers!

Should've commented on these pics when you posted them, I did not, I trust it's not too late now...
These 'might' be a contributary factor to you having 'issues'
with the DZ- product line, and/or operation with TMCC.
The use of 'suitcase' connectors is a {almost} certain guarantee
that you
will have
continuing electrical 'issues' down the line,
which most often get 'blamed' on something else.
As you know, (or should...) :
'suitcase' connectors physically destroy the wire
upon installation, by cutting thru the insulation and conductor(s),
reducing the current carrying capacity,
introducing a high resistance heat generating connection,
and/or a poor, or non-connection, in a low current situation.
Suitcase connectors should
NOT be used with stranded wiring,
as they completely sever many strands of the wire.
These severed strands may act like:
a resistor, inductor, capacitor, transformer, transmitter, antenna,
dependent upon physical characteristics of the wire,
and woltage, current, frequency of signals/data.
Not good.
Used on a solid (one strand) conductor, they will slice the conductor by 50 percent or more.
Also un-good,
for the reasons noted above.
The closest analogy would be a one lane only construction zone on a four lane Interstate during rush hour.
Electrons act like humans under similiar circumstances...(or should I say, humans act like electrons...)???...
Looped wiring under the table will also give you 'unique experiences' when employed in RF and giga-hertz (read command control) circuitry.
Another analogy, ...round-abouts/traffic circles used on some intersections and freeway interchanges around the country.
Yery definately confusing encounter for the out-of-towner, ...electron or human.
