So I am having some pretty consistent corrosion around my positive battery terminal. Thinking I want to tighten all the grounds and perhaps replace my battery cable. Couple questions:

1. I am not sure of all the ground locations. I have the workshop manual "Battery Cables Removal" which I believe shows all the ground locations but I am not sure. Are there any I need to check that may not be covered by those instructions?

2. If I choose to replace the cable which one of these (if any) will suffice? Is only one of these the positive cable? Will I need to do anything apart from reattach the grounds and terminal?

Any suggestions on alternative products and/or strategies?

Thank you.
