Hey Cbozz, the Bluetooth antenna cable is the one with the purple connector, written in the guide as "black and purple FAKRA connector" (sorry for lack of pictures on that step).
If you don't have the purple connector, then I'm afraid your car is not wired and you must wire it yourself (leaving the antenna in the trunk). If you do have the purple connector, take a photo of it plugged in and I'll add it to the original post.
Thanks, and good luck!
