Good work
I dug up some photos, and I’ll try to highlight some differences between AP1 and AP2:
The Ethernet DIAG jack – easily accessible below CID – is a Rosenberger D4Z001-000-B (White). AKA the “easy” port or “Toolbox” port. It seems to be identical on AP1 and AP2. Which makes sense, considering that the service centers / rangers frequently have to deal with both configs…

The DIAG cable terminates differently on AP1 vs. AP2 cars, however.
On AP1 cars, it feeds directly into the back of CID. The connector on the CID side seems to have changed color at some point, because I’ve seen pictures where it’s white and pictures where it’s blue. Here’s the white one:

On AP2 however, the Toolbox cable terminates into the Autopilot 2 ECU (“PX2”). The connector on the ECU side is a Rosenberger D4K20A-1D5A5-D (Bordeaux, or Purple).

As you can see from the picture above, the AP2ECU also has a white Rosenberger D4Z001-000-B. This is, according to the wiring diagrams, “Ethernet Gateway”, and connects to the CID.
On the CID side, the socket should be Bordeaux / Purple color
