No power to bulb

To start off I've lurked here and there a bit on this forum and can't seem to find help to my issue with search functions.

3rd retro I've done on my truck and each has looked better than the last and wiring has gotten much more finicky with each.

Currently:
Morimoto D2S 4.0s with matching harness, xb55 ballasts and 5500k bulbs.

Truck is 9004 and issue is as the title states no power to bulbs. I have 12.5V at the ballast and shutter operates as required when white=ground, brown=low and blue=high. I'm stumped. I've tried swapping ballasts around and tried using the old ones as well as doing the same with the MotoControl box (if that's what you call it). I'm stumped and hope somebody can give me some insight
