You can find the fuse box diagram for a Volkswagen Jetta Trek if you don't have the manual at auto parts stores. You can also contact a local Volkswagen dealer to obtain the manual.
dont know exactly but if you look in the owners manual it has diagrams to show you.. if you dont have a owners manual you can go to a dealership and they should have a diagram that you can look at.. you can also order them online. just go to google and type in what you need and something should pop up..
