I know, but I'd like to start building a collection of my own tools.
So, update! It was a false alarm. . . in a manner of speaking
In order to get it to work on the Forester, I had to actually start the car - against all other recommendations. The instructions specifically said not to, but I tried it on a whim (intuition, maybe?

) and it worked like a charm.
Yay for me?
