This box in the upper right corner is what I'm talking about. Not all Mustangs have them though. Yours may not. But the smaller one below it is on all models. The wire harness running across the vapor barrier is also a know source of noise as there is no attachment point in the middle and it can flap around.
holy shiz that soundskin looks legit! I remember that wiring harness you mentioned, good catch, any tips on getting that secure?This box in the upper right corner is what I'm talking about.

Soundskins is a great product. This is not my car. I cheapened out and used Killmat. Still worked great.
Gotcha, I'll give that a go, any other areas I should check that could be causing my "click/tap" noise from the door?
Let your knuckles find them. Tap everything. If it moves or rattles, pad it, wrap it, or stick it down. Check the metal clips where the bolts go through at the arm rest and pull handle area. Check the back of the plastic door panel for loose rivets. My armrest pad was loose. Ended up hot-gluing a lot of things on the back of those panels.
