gonzo,
Currently using the Digital Window switch(#8969) and works perfectly.
Very easy to hook-up and being adjustable ,you dont have to spend $ or wait,for ordered pills.
Its about the size of a PC unit and you should'nt have a problem stowing it..........
especially on a busa.
Ordered mine from JEGS ........ paid $89.....very cheap and got it in 2 days.
Got help from "bbqb4racin" on install and there are a few posts on this subject,
to help if needed.
