previous owner did some DIWHY that I’m trying to fix, this wiring has very poor contact, fuzzy connection, and the dome light isn’t retained in the headliner when it should be. I ordered a new pigtail connector and dome light assembly from motor craft to splice to these wires, but the motor craft kit has 3 black wires with no labels, very helpful. And I’m not sure what the wiring on the truck is without a diagram. Anyone that has been here or could help me out with finding an answer here I would really appreciate it!
