ok   again  i personally  have  not seen anyone post any  info on this subject.

this  is not a  plug in deal.  all the references  you have  seen to my  knowledge. are  for  the  electric  models.

the  acoustic  while the same   principal  is done  differently

it  requires  you   most likely to cut the  ends off the  new  pickups  voiding there  warantee.  it  requires  you to  remove  the baggs  pickups    voiding any warrantee on your  guitar.  then you  will have to get at the   board  the  original pickups  are  on.  to solder that  new  set of pickups in.  again  if you feel confident   you can do this   then by all means      go ahead.   in the mean time  i can tell you some  people  struggle  with this  stuff  . and  is  best  to have someone  qualifyed do the  install for them.

  i dont  know  you   or  what  knowledge you have   . in other  words  you may work for  nasa  or  you may work for  mc ds.   so i have to give   what answer  i have  for  you.

then again   i see  why line  6   gives  general answers  to people and  no details.  btw  you wont  get anything  from them other  than   they dont  encourage  you doing this .  the reason is  because  there  not   goingto tell you anything   that would  make them liable.   wise  on there  part  from what ive  seen.

anyway  this  is  my take on it  .

in the  mean time  go over to graph techs    site  and   find  your  pickups . i  did  look up  the  vague  manual   and  it  does  say they are two connector  .     the  baggs pickups    have either   2 or 3  wires     there   manual  is  less  clear than   graphtech . graphtech  would  most likely  have you  buy there  acoustic board  . about the  size  of two postage   stamps  and  have you connect  the pickups to that  and the board  to  where  ever. but   interconnecting  this   board  to your  variax   could bering  you more  problems.

in short   if your not having  problems  with your  guitar..  best   to let  sleeping dogs  lie  ay

good  luck.
