We bought our 2019 Thor ACE 29.4 in August of this year and discovered this little device dangling from the cornice over the dinette. There are three wires/line/cables. One end of the wire (see attachments) is an electrical plug-in which is plugged in behind the TV...the other end I traced to the exterior wall (unable to trace further). The third wire/cable appears to be a plug-in like for charging iPhones or for a connection to another device. Not even sure how to describe this apparatus, but I know there are some knowledgeable techies out there that will recognize this "thing". Hopefully you can view the attachments (pics) and tell me what this device intended purpose?
As mentioned that is used to control most likely a LED strip light behind the valance where the one cable is jammed. The other end is an infrared reciever to get the signal from the remote... find the remote and you may have some 'sexy lighting'.
