Hi,
You can create a new custom HTML module and put this content output for it:
<iframe width="350" height="197" src="https://www.youtube.com/embed/2j8kPyqM7Eg" frameborder="0" allowfullscreen></iframe>
in Advanced tab, put this class suffix: module-dark
Try to disable the default editor first in Global Configuration, in case that it strips HTML tag in custom module.
Then assign this module to 'position-7' position.
Regards
