The same thing happened to me, at least there are the following harnesses: harness for 4 sensors harness for 6 sensors harness for 4 sensors + anti fog harness for 6 sensors + anti fog all those variants with front camera and then with right and left-hand drive. If it is only for 4 sensors, buy the cheapest one and do not connect the rest. Another option is to buy 4 PDC connectors and make the harness yourself, in fact it is the easiest.
Look at this reference,
it's the simplest one I found.
It has 4 sensors and the fog lights.
