S54 engine wiring harness help.

Hi guys, I'm swapping the S54 into another car and am a little stuck right now. The engine wiring harness doesn't seem to have a leg for the oxygen sensors and thermal sensor. Does anyone know what part number this additional wiring harness part would be ?



RealOEM shows three harnesses

* 12517831197 - wiring harness, engine ignition module

* 12517831637 - Engine wiring harness, engine module (I have this one already).

* 12517831760 - wiring harness, engine trans. module
