So you don't want to know why it might work, just how to do it. Okay.So is anyone going to spare us the long ass post and just put a pic of where to plug the booster lol. Holy crap that was a whole lot of info for a simple here plug your booster here.
Connect the positive of the booster on to terminal N1 in the Power Distribution Center, and the negative of the booster on the collection of negatives cables connected to the main battery's negative post, only disconnect those negative cables first from that main battery's negative battery post before attaching the negative of the booster to those cables.
The, err, "long ass post" tried to explain the theory behind this. That takes words, especially for the unfamiliar. Sorry, not sorry.
In fairness, the post could have used pictures. Also in fairness, try explaining an chartered idea to the masses in ways all can understand Ruben. Then get shat on; see if you want to do that again. Just sayin'.
