A couple small points which may help to sort when first looking at the drawings or the batteries as there may seem to be confusing mess when first looking!!
There really is some reason for them marking things. The cables (when new) were marked with either tape wrapped at the ends or sometimes simply black and red as the insulation colors asnd those colors are then shown on the drawings for sorting which should go where and what they connect at the other end.
But first step is to sort which chassis you have, Workhorse or Ford in your case. Cuts confusing if we can start with looking at the correct info.
Then I didd a markup of what info the drawings may have to match up with what you actually find. This is assuming folks have not switched out or changed too many things, of course!
