Integra sequential tail light mod?
 

I know it can be done my question is how? I'm modding my tail lights right now and i saw the video of someone doing it on a four door just wondering how i can do it,are there any electrical genius that can possibly figure it out since I'm stumped? some diagrams or something in that aspect that can help since the guy who posted up the video isn't really trying to put his method out there.
Thanks ahead of time.
