I'd think that anyone running Jerry's N1 <-> N2 fused jumper hack, like you had prior @WranglerMan Will is apt to not be a great ESS fan--or at least a great ESS/Aux battery fan.
But that said, for all its ingenuity I'd also be apt to expressly disengage ESS with it installed, either by non-latching factory button push at cold crank or 3rd party gear.
I say this because it seems that with this hack installed, tests of the ESS battery prior to or during an ESS event might be a composite reading of the voltages of both batteries. This could lead to ESS events that might not occur, or remain in effect as long if ESS is activated at traffic stops, were the ESS batteries isolated as is the case from the factory.
This is NOT a stab at the hack. It's simply to say that at times workarounds sometimes have--as they say for medicines--contraindications--or situations where the benefits of its use can be outweighed by other factors. We don't want to drain the cranking battery in ESS events that normally wouldn't occur, or run as long, were the jumper not installed and the ESS battery managing *most of the power draw of an ESS event, presuming the main battery for engine cranking after the event ends.
*(I think at one point Jerry said that some operations do tax the main battery during ESS, like power steering.....as much as ESS won't engage if the steering wheel is turned.)
