Keep an eye out for unsecured live wires in your trailer. Found this live 12v wire in the front left cabinet. Thankfully no electrical fires were started.
Think the factory would at least put some electrical tape on the ends of the wires to prevent contact.
Just found it cleaning out the trailer today. I just put some electrical tape on the wires. Eventually I will need a 12v power supply for something. Would install a 12v outlet like you suggested but have enough of them already.
