When connecting your battery terminals you should connect the positive battery cable first and then the negative because it prevents a short circuit which could blow a fuse or damage electronics.

I would first put some anti corrosion on the battery terminal ends first to help keep the connection from corroding.

So attach the Red Positive first and then the black negative cable last.
