Does anyone know for sure, if my US design Yaris LE hatchback what I want to do is convert my headlights to auto lights. Does anyone know of, when the cars are built, that they put wiring harness to accept all accessories? ( nav, auto headlights, up graded sounds from factory)
i want to buy the light switch with auto lights. The light sensor if necessary, and I know the switch will fit no problem, but for the manufacturer put the wiring in the harness to make the auto lights work? Also, I looked under the little plug on the dash it’s only a plug currently no harness would the connector possibly be trapped under to the harness?
i need to know
