ok I am trying to figure something out in this book of mine it's the haynes repair manual back in the very back of this book it has the diagrams of all the wires and colors and everything else but my qustions is that down at the bottom of every page it has a few lins that are marked with a leter do these lines indacate a ground line or do they mean something else? Haynes does not clearly state what these lines are running to any ideas?
