Customer Question

Had my battery stolen on a 2008 bayliner deck boat. I'm trying to figure out which wires go to positive and negative. There are a few red and black I'm assuming go to there respective terminals and two yellow that one has a tag that says negative. Where does the other yellow go and I've got one that is completely covered with plastic wire loom I'm guessing goes negative and one that's red and black that has bilge pump fuse blocks that I assume go to positive. Please help
