Tekonsha Prodigy trailer brake controller

Since the Tundra is not equipped with a factory trailer brake controller and recommends the Tekonsha Prodigy. Does anyone know the best place to install it? Seems a bit bizarre that this very well engineered vehicle that is designed to tow does not have a factory trailer brake controller. What is worse, it has a hookup and place for an ipod but I cannot find a neat place to install the Tekonsha Prodigy trailer brake controller. If anyone has installed one, can you send photos? Thanks!
