demographics and Challenging : where to insert the code ?

Good evening . We have a question about inserting code about. here is the question :)

We use google analytics at our website. Since we use the Module not placed anywhere manually code as suggested by google.

We want to include the "demographics and Challenging" and google suggest to change a line of code. (this line – > ga.src = ('https:' == document.location.protocol ? 'https://' : 'http://') + 'stats.g.doubleclick.net/dc.js'; )

The question is where we should make the code change? Does this works through the module?

Thank you a lot for your time .
