My father picked up this mustang about a year and a half ago, and i noticed it had defrost strips on the rear glass, but no buttons where the defrost button, traction control button and fog light buttons would be. So upon looking for connectors in the car, I noticed three of them(brown, pink, and grey). My questions are, what colored connector goes to what, and if i were to find OEM buttons, would all three work correctly?

Any help would be much appreciated! 😊
