I've decided to buy some parts on ebay to convert my car to power windows. However, i cant find the power door harnesses i need. My car came with factory power locks preinstalled and i was wondering if they include the wiring needed for power windows already in the car even though it only has power locks and manual windows? Anyone else have any idea or knows if the wiring for power windows is already there on a car that came equipped with power locks but manual windows? thanks.
