I think you always use the higher class highway's links.

linking a motorway to anything uses motorway links,
linking a trunk to anything but a motorway uses trunk links.
linking a primary to anything but a motorway or trunk uses primary links.
There are no secondary links (which causes issues sometimes, I think).
