How do I connect my family search account to the free ancestry.com site?
I am just another 'lowly' User/Patron ...
Just in passing ...
The "Commercial" Website, of "Ancestry.com", is NOT ... FREE ...
The "Commercial" Website, of "Ancestry.com", is a "Subscription"/"Paid" website.
One, can get FREE access, to MUCH (but, NOT "All") of the "Commercial" Website, of "Ancestry.com", by a personal visit to, a "Family History Centre" of the Church, around the World; where, such access is available.
I hope, that this may help/assist, somewhat.

How do I connect my family search to the free ancestry.com?
Maybe you are referring to the free Ancestry.com accounts for Latter Day Saints ?
Again, as with visiting FHCs, this does not give you free access to the entirety of the website.
However, since I am a not a Latter Day Saint, I don't know how to set this up.
In case your question is about setting up for DNA genealogy work:
The secret sauce is the tree. For that see this other Discussion: Conflicting tree info
