Javascript onchange event listener changes text input field value for Wordpress

I have some custom drop-down menu's on a Wordpress powered site. When a user is adding a new post they will add 3 details to the post using the drop down menu's. For example one select box might look like this:

<select id="car-make">

<option value="Volvo">Volvo</option>

<option value="Ford">Ford</option>

<option value="Toyota">Toyota</option>

</select>

After the user chooses from the drop-down I want it to automatically add the value to the blog posts 'tags'. I can't modify the code that outputs the select box's else I might add <select id="car-make" onchange="update_tags();"> so it would need to be a function inside the <head> tag that listens to the specific <select> ID's and then changes the value of the <input> ID when the event happens.
