Nissan ECU Tuning

We have a problem with a zed not being able to shut down. Starts fine but when the ignition is turned to off, the engine continues to run. Conzult gave no errors in the ignition circuit The ecu to my way off thinking is working, as it should.
The t timer was disconnected, made no difference. The question is this. There is a black and yellow wire running from the ignition switch in the start position, to the ecu @ pin 43, is this wire an earth? Could someone shed some light as to what the B/Y wire dose?

In that case the ECU is most likely defective

swap it with a known good one to verify
