Okay - here goes....
I started on the passenger headlight assembly. I had already used my 2017 Focus Electric Wiring Diagram Manual to figure some things out and learn that Ford did not follow their manual with these headlight assemblies. These headlights have HIDs.
Remove the two bolts and connector from the headlight assembly:
Now take the assembly to your bench and remove the shown rubber cover. Right underneath it is the H1 socket. Remove it. It has a hot wire but no grounding.
