There's an extension cable that you will need to route from the back of the radio to the passenger side and up the frame to the soundbar. It is my understanding that if your vehicle did not come from the factory with the equipment for Guardian, you will not be able to install it and get it functioning.I bought the antenna, so is there a connector on top of the rollbar under the roof? Or is that just where it normaly is located and i will have to run my own wire???
