My pigtail* supplies (black lead) power from the onboard battery and, if plugged in, from the Atlas. It jumps +1.3 volts and the bus shows 14.42 vdc upon starting the Atlas. So there is at least some current there.
I don't have time now to put a DC clamp meter on that wire to see the amps/milliamps but I expect it be less than 6 0r 8 amps given the OEM VW wire size and slow tach (idle rpm).
Yet, it is fine for the current draw my small fridge takes in my SuperLite 19' camper.
I don't know yet if the black line remains powered when you park or if a timed "load-shed" switches it off.
The Tekonsha P-3 EBC works perfectly in this configuration.
