Help Implementing Google Search Engine

So I have this search method, it simply uses google to search my website.
But i'd like to use my Google Custom Search Engine instead.


Here's my search engine unique id:
Search engine unique ID: 008729583548452524559:cxs7ncn4fyg


Here's my search engine code google gave me:

Paste this code in the page where you'd like the search box to appear
[code]
<!-- Put the following javascript before the closing </head> tag. -->
<script>
  (function() {
    var cx = '008729583548452524559:cxs7ncn4fyg';
    var gcse = document.createElement('script'); gcse.type = 'text/javascript'; gcse.async = true;
    gcse.src = (document.location.protocol == 'https:' ? 'https:' : 'http:') +
        '//www.google.com/cse/cse.js?cx=' + cx;
    var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(gcse, s);
  })();
</script>


<!-- Place this tag where you want the search box to render -->
<gcse:searchbox-only></gcse:searchbox-only>

Code (markup):

Paste this code on http://, where you'd like the search results to appear.

<!-- Put the following javascript before the closing </head> tag. -->
<script>
  (function() {
    var cx = '008729583548452524559:cxs7ncn4fyg';
    var gcse = document.createElement('script'); gcse.type = 'text/javascript'; gcse.async = true;
    gcse.src = (document.location.protocol == 'https:' ? 'https:' : 'http:') +
        '//www.google.com/cse/cse.js?cx=' + cx;
    var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(gcse, s);
  })();
</script>


<!-- Place this tag where you want the search results to render -->
<gcse:searchresults-only></gcse:searchresults-only>
