Next we have to connect the wires in the cockpit of the car. I have a PDK. I won't tell you have to get the factory radio out as there are other posts on that. However, I will help you get the center console out since you'll need to access the parking brake wire (this connection disables video when you are driving) and I ran the AUX input to the stereo in the same spot as the existing AUX connector in the back of the armrest. This AUX connector won't work anymore so I drilled a hole and ran my AUX connector to the back of the armrest. By the way, your steering wheel controls won't work anymore and there isn't a Datalink adapter for the Porsche but I think that a backup camera and Carplay is more important than the steering wheel controls.
I had to get the steering knob off the PDK shifter and to do this I put the car in reverse and turned the little coupling at the base of the shifter and pulled straight up. It came off:
You'll need to tap into the parking brake yellow wire below the parking brake handle to run this to the stereo:
I ran an AUX line next to the old AUX line:
I also drilled a hole in the little tray and ran the Lightning and Android micro-USB wires from the stereo through the tray
and I store my cables in it:
Next post is about the rest of the wiring in the center dash.
