I had bookmarked this link a while ago but haven't tried it yet. So I don't know whether this works. http://tinyforge.org/docman/view.php/22/3/tinyerp_ez.pdf
Nope. I originally wanted to do so but up to now I always used EZ on its own and haven't even looked at tinyerp beyond installing it. So I can't help you with this at all I am afraid.
This pdf doc is related to the first version of the connector
http://ez.no/community/contribs/applications/tinyerp_connector The newst version have more options but is lacking in install doc. Hope to have it within 2 weeks (if you can wait...)
