I'd like to create a UMC extension cord that would connect to the UMC on one end, and the UMC adapters on the other end. The cable would pass the pilot and other signaling necessary for the UMC to deduce the correct charging rate based on the attached adapter. This seems like a safer (although still not "official") option than a NEMA 14-50 50 AMP extension with "dumb" adapters that then connect to other (potentially <50 amp) plugs.
Anyone know where I could find the necessary male and female connectors to mate to the UMC to build this, short of cannibalizing a UMC and adapter?
