Google maps function without a plugin

Hi guys,

I need to implement Google maps into this website without using a plugin, though I have a custom written jscript function in my scripts.js.

Now i’m left puzzled on how to make this visual on wordpress. What I tried so far is this, and i’m not sure how to otherwise.

//Google Maps
function gmaps_header(){
?>
	<script type="text/javascript" src="https://maps.google.com/maps/api/js?sensor=false"></script>
<?php
}
add_action('wp_head','gmaps_header');

function gmap() {
if ( is_page('contact') ) {
	    wp_register_script('initialize', ("". get_template_directory_uri() ."/scripts/script.js"));
	wp_enqueue_script('initialize'); }
}
add_action( 'wp_print_scripts', 'gmap');
