I am finding out there is more to this than I thought.
I have bought the steering wheel switches, clock spring, and servo / cable.
I was hoping the wiring harness would be in place.
It used to be common practice at Ford to make only one wiring harness per model and just not connect those options not installed on a particular vehicle.
Guess that isn't the case anymore.
Her car, being a 2007, it is going to be hard to find the harness.
I would be more likely to replace the entire wiring harness then to try an piece it together.
So much for an easy install...
