Blog Types and TOS plugin - how to add code to custom signup page

Hello,

I am utilizing a custom wp-signup.php file in my theme by using my htaccess to redirect the sign-up page. I had followed this process: https://premium.wpmudev.org/forums/topic/wp-signupphp#post-39782

That had all worked great, except now I've added the Blog Types and TOS plugins and am having trouble getting them into my sign-up page.

Can anyone help me insert the proper code for the Blog Types and Signup TOS plugins into my wp-signup.php page?
