So yes: drawing-up a schematic that would bypass the immobilizer for a remote-start DOES, in fact, teach us how to steal cars, despite the fact that a thief would still need to do the easy-part of circumventing the steering-lock.

Both of these paragraphs are close but not quite correct.
The key bypass REQUIRES A KEY.
Second, it is NOT drawing up a schematic to bypass the immobilizer. That is NOT what I am requesting and the whole idea is a bit ridiculous. The key bypass uses a key and RFID. Just like when you start your car with a key normally. It USES the factory immobilizer (like a normal crank with key). Asking how to wire the car properly ... is how the factory transponder ring is wired in NO WAY facilitates theft. Wiring it so it still requires a key is not an option. It is always required. It’s how a key bypass works (at least in this Porsche ... some other cars, including the cayenne, can do so through firmware. But even that does NOT bypass the immobilizer).
Once again, these comments suggesting that I am looking for how to wire around the immobilizer are simply not accurate. They belie a fundamental misunderstanding of how a DEI 556U module operates. And getting proper instructions for how to install and wire a 556u would not facilitate theft any more than getting instructions for how to wire up a car audio system.
