My S60 has only 1 controller, the other one (small on the side) is not a controller, it's balancer and not a controller. I don't know what is the purpose of other ones on your car.
You mentioned that you switched the headlights but you did not say if you swapped your original all 4 controllers from the original headlight to the used one you got. If you have not, try that after verifying that you don't have short in the wire.
I tried swapping all the controllers one by one to my old headlight and didn't help. It could be defective as well, who knows.
