Spektrum DX8 and DX6i Buddy Box Setup "How-To"

I couldn't find a video that really explained it for me. I got confused. So, I got my cable out and tried to figure it out. Here is what I came up with in this video
If this video will help just one person...I'm satisfied!!! If this video helps more than one person...that's just awesome!!!
