Big 3 + Starter wiring (How to)

Extra grounds is always good and helpful. I'm assuming the bad idea bit comes from the added alternator to battery cable. With this upgrade, we're not removing the factory charge wire, just adding another, correct? I'm thinking this guy misunderstood.
Has anyone with an F150 and the battery saver feature done this upgrade? With what results?

I could see where there would be issues tho with the battery saver since it probably has signal wires that run to the ecu and a couple extra relays in there so just adding another wire could potentially by pass that.

You might be right...but I can't find any info on it...12 gen section it is. Thanks.

Here you go.
I replied to another thread that this thread was linked in...but to expand the horizon in an attempt to get an answer...
So, I recommended this upgrade on another thread dealing with the 2015 ecoboost, particularly to solve an Auto Start stop issue where the auto start would not engage because it was charging the battery, and another member said that doing this upgrade was a "really bad idea" and to go read about the battery saver function. His only response when I asked further was "did you read the info?" for which I haven't been able find anything since...which is why I asked further (duuuh). Any one know anything about the Battery Saver system and why this is supposedly a "really bad idea" for the Ecoboost?

Reguardless of "battery saver" if you strickly connect the alt to the battery, ground to the negative, and ground to engine block you are doing nothing that is not already connected. Their are no breaks or relays in that system from the factory. You won't hurt a thing, you are just adding wire or replacing what is already there making it more efficient and capable of providing more power.
The battery saver runs through a different circuitry. There is always positive voltage and batter running from the battery to the starter relay, which is directly bolted to the alternator positive lead.

I don't want to sound like the dumbest guy ever and I know this is an old thread but...
Why are we installing a fuse here? My guess is that the new thicker wires can no longer replicate the "natural fuse action" that the stock wires can. ie: burn up and open if something goes haywire.
