GAnalytics module 1.4 in 1.6.1.0 how to add ga(\'require\', \'displayfeatures\')

[Smiles]

I could not get the new analytics module working in 1.6.1.0 . I read a lot of topics but nothing worked. Now i'm back on the  old 1.4 module. As advised in this topic. https://www.prestashop.com/forums/topic/386446-google-analytics-202-not-tracking-after-update/page-3 works perfectly until now. 

 

But I want to enable remarketing. In the latest module I fixed this with the following.

 

I added: ga(\'require\', \'displayfeatures\'); to the script ganalytics.php

<script type="text/javascript">
				(window.gaDevIds=window.gaDevIds||[]).push(\'d6YPbH\');
				(function(i,s,o,g,r,a,m){i[\'GoogleAnalyticsObject\']=r;i[r]=i[r]||function(){
				(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
				m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
				})(window,document,\'script\',\'//www.google-analytics.com/analytics.js\',\'ga\');
				ga(\'create\', \''.Tools::safeOutput(Configuration::get('GA_ACCOUNT_ID')).'\', \'auto\');
				ga(\'require\', \'ec\');
				ga(\'require\', \'displayfeatures\');
				'.($back_office ? 'ga(\'set\', \'nonInteraction\', true);' : '').'
			</script>'

Now i have the old file but how can i add it?
