the picture at the bottom of this page http://1968firebird.org/illustrated/acclink/acclink1.html says all 69-67 have the same setup, slightly differing depending on transmission. i've never messed with mine, so i'm not much help. that page also says it is for floor shift with std trans. i couldn't find one for auto. it's probly the same. or maybe it's in the tranny?
there is also a wiring diagram on that site. it shows a lime green wire going from the bulbs to the backup switch, and powered by the same wire as the flasher, out of the fuse box. ------------------------------------------------------------------------ sometime later that day...
