I just got my Bash bunny today and started digging in. I was getting the dreaded red light with the latest install tools off the github page. Turns out you also need the latest bunny_helpers.sh in your library folder as well to pick up the SWITCH_POSITION variable. Once I got it moved over, the installer worked perfectly. It took much longer than it should have to sort that out. It was fun digging into the guts and starting to figure out how my BB works though!
