What is the equivalent size (metric or SAE) open ended wrench for pedals?

15mm for all but pedals on the Ashtabula one-piece Schwinn Varsity -type
crank, as far as I know. In other words, almost certainly 15mm.

Also, is there a convenient website for steps on installing stems/quills
on a threaded steerer? don't know if sheldon has this info, his site is
too large to navigate sometimes .

I don't understand - are you looking for subtle stuff? grease contact
surfaces, stick stem in fork, tighten binder bolt. I don't know if
there are torque specifications available; you can overdo, but it takes
some effort. Pay attention to the minimum insertion line.

Good luck.
