Help with 6 vertical sticky pistons

I've been fighting with the wiring and repeaters for almost 12 hours now trying to get this work and I give up. Has anyone built this or know where I can find some wiring diagrams or a downloadable world? Youtube is a plethora of 2 and 3 stack and the 13 stack that is posted in the wiki (with absolutely no information on how he built it).

Thanks for anything you can provide.
