Where did you come up with "Selective Switch Service Tool?" And why do you want it?
If it exists, your dealer's service department should have one or at least know how to get it. But Mazda does not use this name for any of its special service tools (SST) in my 1995 Workshop Manual.
It IS in my 1990 Workshop Manual. It's for diagnostic purposes. They show a picture of it, etc.
Anyway, thanks for the response. We are going to check further about this. :) ~Cissy My '90 Mazda Miata I love PC adventure games
