Hi, can anyone help please. In the process of putting the engine back in the car today, I noticed this.

This is the wiring from the main loom (on the car) that connects to the lambda sensor. The connector the wires go into is marked A B C D but which wire goes where? Not to confuse, I don't mean the small piece of wiring running from the actual lambda sensor like the link below. It's off the main loom on the engine. Thanks
