I'm no EE but I DID drink a pile a beers when I installed my link 10.
Trying to recall how I did it and being away from my tarped up boat I remember the link 10 as a kind of stand alone unit. I hooked it up to my batteries, also 4 6v, and the shunt was installed very close to the batteries, right in my custom homemade battery box. Then I ran all the wires to where I wanted the display mounted and plugged them in. I think the only thing I had to plug the wires into besides that was my charge controller, nothing with the existing shunt.
I just followed the directions and it's been working great ever since. I might have bought extra wires made specifically to go with the link 10 because the run from the batteries was so long.
