Subaru Wiring Diagram Ecu. In 1995 Subaru cars switched from OBD1 to OBD2. To do this I have to take out most of the wiring harness which runs the EJ22 22L H4 engine which comes standard in the 96 Impreza and install the engine side wiring harness and ECU from the SVX into the Impreza.
Remove Vanagon Engine 5. - The harness is packaged with a copy of the wiring diagram installation instructions and a copy of the original specification document. Here is what the ECU connector and plug looks like.
