As was suggested over on FTE obtain a schematic and use that for not only this project but any others of a factory-original wiring concern. Like this one: https://www.ebay.com/itm/2013-FORD-V...gAAOSwbK5fyU0a
As I suggested on FTE this sort of manual is invaluable because it contains actual circuit schematics it also includes plugs, connectors along with images of where they are and how they would appear visually.
Contributions such as CarringB are great but having a factory wiring diagrams book in hand is usually the perfect and immediate resource for such modifications. In that instance you'd be able to see which plugs he mentions and pretty much go right to them.
I've used EVTM's exclusively and they've be invaluable for the crazy circuits I've added or modified over a few years.
