Location of the remote relays

[j.w.]

I have a 2017 Sprinter Campfire edition travel trailer. Everything on the remote works except for the awning lights. The awning lights do operate from the switch on the switch panel. I have not been able to locate the relays or control board that the remote "talks" to. I have searched this forum for the keywords that I can think of without any luck finding an answer. Any idea where the relays or control board is located?

The remote control receiver is probably mounted on the roof of the passthrough on the curb side of the trailer. It'll look something like this photo.

Thanks for the quick reply. I'll check it out tomorrow!
