Below are the Ford wiring diagrams.
The wiring goes from the multifunction switch to the bulk connectors sending the power outside to the Day Time Running Lights relay block if you have it and then back inside the vehicle to the fuse box. That is where the transition is made in the wiring color. The day time running light relay block is located behind the dash on the passenger side. There should be a panel on top of the dash which is kind of oval that pulls up. It is clipped to the top of the dash.
Make sure you have power at the relay block with the low beams turned on.
