The 400L ia indeed the 40 track version of the SA-400. IIRC the 400 (no
L) did not work as a 40 track drive.

I can't help with details of the SA-400 <> Heathkit interface, however I do
have the full SA-400 OEM Manual up on my site - it's in my Altair section,
go to "Documentation" and then "Reference Documents" - this will tell
you all about the jumpers and interface requirements.

Regards,
Dave
