If someone has replaced the Curt - here is a question - does the Curt splice MB tail light wires, or does the Curt feed the tail lights
If it splices the MB wires on their way to the tail lights, then the Curt could be removed.
If it doesn't splice the wires, then perhaps because the tail lights are LED's, the Curt is required to drive them.
