I am looking to install a second battery in our 187. There is a 1/2/both switch already installed, I am unsure of how to connect the battery. There is also a positive cable for it. In the battery well, there was a black cable unattached to anything. Would this be a ground wire for the second?

Here's a link to a really good video explaining setting up a two battery system with selector switch. You may already have the battery cables in place for the setup if the switch was installed at the factory.
