Mapping custom attribute from magento to odoo

[CemAmixys]

Hi Community,

I installed the module "connector-magento" (OCA) in odoo 10 and currently I can synchronize data from magento to odoo.

My next step, is mapping of magento custom attributes (like manufacturer) in order to use them in odoo.

For the moment, I can get the manufacturer attribute from magento to odoo but in database I have the id of manufacturer for a product and not his value.

I use this tutorial for the mapping : http://odoo-magento-connector.com/guides/tutorial_customize.html

Someone can help me to get the value of this id ?

Thanks
Cordially
