Thank you for the vote of confidence and welcome to the forum. The black wire is listed as going to the alt output post and leads straight back to the fuse block. As for the red wire it leads straight to the right side of the Maxi that is blowing. I attempted to switch the red in junction with the blue wire which appears to be how one of the diagrams depicts, but another Maxi blew even worse.
