I guess i just assumed they would be on the inside, It does`t say inside or outside in the catalog but the picture has them on the outside. I guess I should have requested inside not assumed they would be. I don`t want them with the sensor outside I hope I can return them, I just opened the box today the headers are still in the bags.
