Harris, I took a look at the other mod. The audio pins shift one down when passed through that middle "stick of gum" board.. I remember noticing this ('cause I completely disassembled my unit first time for modding) In this mod, the interception is done before that board.
** also please take another look at the other mod post, I'm confident the pins do not change between years. As long as it's a RF 6 disc you are okay.
