Drupal custom node type add field to relate content
I found the answer, there's a module named Entity references, this allows you to add and Entity Field in your custom node type, and with this you can relate to another contents. To use it you just need to add the field, select what do you want to point to, an that's all. To render the entity field and it's fields you need to add to you tpl something this:

&lt;?php print render($content['field_myentityfield'][0]['node'][62]['fieldof_entityfield']['#items'][0]['value']); ?&gt;


You can check it with devel.
