Fox Plug wire management

Zip tied made wire looms. Cost effective and looks quite nice.

I need to make another set at the bottom. Maybe I'll do that tonight.

I couldn't pay $40 for wire separators. I just used the ones that came with my MSDs, or from the parts store. They pop on and off very easily, too.
 
You should be able to get a set of the valve cover bolts with the factory wire holder provisions on almost any 5.0 equipped vehicle. Could grab them off a Crown Vic if there is one in a yard near you.
