I'm trying to add a "register" link in an admin bar login

I'm trying to add a "register" link in an admin bar login plugin.. but for some reason there isn't a register link so I was trying to add one.

I copied the "lost password" code to create a register one and changed what was needed.. but I'm not sure how to get the register button to link to my register page! What code do I need to put in the "href" to get that to work? thanks!

$wp_admin_bar->add_menu( array(
'id' => 'lostpassword',
'title' => __( 'Lost your password?' ),
'href' => wp_lostpassword_url()
) );

$wp_admin_bar->add_menu( array(
'id' => 'Register',
'title' => __( 'Register' ),
'href' =>

) );

This is what it currently looks like

I want to link it to wasecaconnect.com/register
