I hooked up my trailer to the back of my 3S and while I was going down the road at night, the gauge lights went to "day mode" and the radio and climate lights went out. I also found out all my tail and front parking lights are also out. Both taillight fuses are OK. Map and trunk lights still work. It's like the car cannot sense that the headlights are on. Is there a relay or fuse that controls this?

please help!

There is TNS relay ( R28) BUILT INTO PJB. This relay is the one controling day/night mode of interior illumination switching and also tail( position)/front parking light.

If that's the case ( TNS relay is out) could be expensive fix... as I mentioned in first line, relay nuber #R28 (#R22 to #R34) are built into PJB and I am afraid you might have to replace relay/fuse block itself.
Talk to your dealer to see if problem is caused by TNS relay or not first, and then ask if it's possible to just replace TNS relay.

Thanks so much for the suggestion. If replaceable, which one is it (location wise)? If PJB needs to be replaced, do you know what years and models might be interchangeable with my 04 S Sedan with ABS? Again, thanks so much!
