OK, despite scouring my reference books on DC wiring, I can't answer a small-but-important question:
The recommendation as I understand it is that every 'endpoint' should be powered with an independent pair of wires from the buss.
In my case, I'm installing a TINY fan for my Airhead vent hose (sub-sub-1-amp), and I can either (a) create a "Y" off the wires which are powering a little-used DC outlet, (b) try to disassemble a teak 'airway' used by the current (large and powerful) head vent fan, and use that set of leads, or (c) decommission the power outlet and just steal its leads.
The most likely use of said power outlet would be for a larger fan, still only 1 amp, so I would think that choice (a) is reasonable.
That said, I find that honest ignorance is the only sound path to enlightenment... and I got plenty of the former, lol.
What say ye, mateys?
