I am installing a brake controller and 7 pin connector on my 07 Tundra. I just purchased the truck and the original sticker was in the glove box. It states that the truck came with a sports package option and the tow package was deleted as part of that package. In searching the form I learned about the 4 pin connector behind the bumper. I checked tonight and sure enough it was there. The pigtail plugs into a connector mounted up and back from the bumper. Right along side of the that connector is another two wire connector coming from the front of the truck with nothing plugged into it. Could those two wire have been part of the tow package wiring that was deleted?
