I changed mine out last spring. To help make sure I put things back in the same place, I drew a quick sketch of my four batteries, numbering each battery post and noting which way each of the eight battery posts were facing (right side up or upside down). Then on the actual cables themselves, I used a "sharpie" permanent marker pen and marked each cable with the number (#1-8) of the corresponding post to which it was attached. In some cases there was more than one cable attached to a post. Worked well. Kept things properly sorted. Good luck!
