Porsche PDK (7DT45) — Wiring
This page describes how to connect a Porsche 7DT45 PDK control unit and its shifter to IOcan. Before wiring, familiarize yourself with the general Wiring Concepts and the device pinout.
Unlike the BMW transmissions, the 7DT45 uses a single CAN network for all communication between the control unit, the shifter, and IOcan, plus a LIN serial line between the control unit and the shifter.

Pin descriptions
CAN-H / CAN-L
These pins are responsible for all communication between the 7DT45 control unit, the shifter, and IOcan.
Serial
This is a LIN network that needs to be connected to the shifter serial line.
Shiftlock supply / Shiftlock −
These pins are responsible for unlocking the shifter for engaging a gear.
KL15
This terminal has to be connected to the WAKEUP OUT pin on IOcan.
KL30
This terminal has to be connected to KL30B OUT on IOcan. This is a current-carrying connection which has to be made with wire of 2.5mm².
KL31
This terminal is ground for the transmission. This is a current-carrying connection which has to be made with wire of 2.5mm².
