I am running 12 volt cable to the front of my crawdad for my trolling motor(mounting the trolling motor plug) but also putting a 12 volt plug (and maybe stereo) up front too. How should I split the cable once I have it ran to the front of the boat? Maybe no stereo since I only run one battery, but still want to split it to at least the trolling motor plub and 12 volt plug.
