Need help with code to remove autocomplete in checkout

What I have: WP 3.8.1, Mystile theme and WC 2.1.2

I need assistance if figuring out a function to disable the autocomplete/auto fill of the checkout form. This is the code I found that I believe needs the function/action added to my custom functions.php

16 class WC_Form_Handler {
 17
 18     /**
 19      * Constructor
 20      */
 21     public function __construct() {
 22         add_action( 'template_redirect', array( $this, 'save_address' ) );
 23         add_action( 'template_redirect', array( $this, 'save_account_details' ) );

I don’t use accounts on my site so that wouldn’t apply for me. The first one to save address is the one I believe needs to be used. Am I correct? And can any code savvy person out there help with stopping the save address in the checkout fields? Thanks!
