Read the full internal flash (via Boot Mode) and the 8-pin EEPROM (95320) from the original original ECU. Write both datasets directly into the donor ECU. This creates an exact software replica, making the donor ECU plug-and-play without any extra programming. 2. EEPROM Swap

When interacting with the main ECU interface harness, you must reference the exact plugs (frequently categorized across standard triple plug formats Plug A, B, and C). The primary critical functional points to interface safely with your hardware bench tools include: Pin Designation Target Cable / Connection Requirement Functional Purpose +12V Direct Constant Power Supply Unswitched Battery Power ( Plug C - Pin F4 +12V Ignition Control Switched Ignition Simulation Signal ( KL15cap K cap L 15 Plug C - Pin H4 Chassis Ground Connection Ground Reference ( GNDcap G cap N cap D Plug C - Pin B4 K-Line Serial Communication Wire Communication Diagnostics Link me7.4.5 pinout
