Getting read to install Terrova 80 lb thrust. The boat is already wired for the motor, however I am converting from 12 volt to 24 and have to connect the 2 batteries together. Do you guys recommended buying the wire from any certain place? Should I buy the ready to connect ones like Cabelas sells or just buy the wire and connectors separate and do it myself? Just seeing what everyone does and where you buys your wire and connectors? Thanks
