A 1/2" ratchet and you're good to go.
It IS a breeze.

First, when I was composing my response, I only provided the routing for the 7.3L PSD. Then I figured since ZBeeble has a 6.0L, and he also posted in this thread, I better also include the routing diagram for the 6.0L PSD's.
THEN I figured someone with a 6.8L gasser would post up eventually (today, tomorrow, next month, next year after digging up an old thread, etc) and ask if I could provide the routing for their gasser.
So I used a shotgun to kill a fly. All in one post.
