The #1 has no power! The plug has not been fired at all. No voltage shown at all on the coil

2012 Limited with 3.5  154,000 miles

Engine developed a miss fire on #1 replaced plugs,  coils  and injectors. Still had misfire.

sent out pcm. Get new pcm and replaced with another set of coils… still has misfire.

Start ohm testing wires and find that I’m getting readings on multiple wires on each coil with all the coils and injectors disconnected, disconnect the engine to ignition harnesses and the issue goes away…. Test the ignition harnes and I have 5 wires that ohm test together. 
 

In desperate need of a wiring diagram! 
Any help greatly appreciated.
