Hey Charlotte! It sounds like you're describing the Westbar 4-way which I have attached a picture of below. While we do not have the replacement plug you're needing we do have a couple of options that will work. The 25 Ft 4-Way Trailer Wiring Harness item # A25W2GWB you purchased will work if you're wanting to rewire your entire trailer or just cut off the plug.
Or you can use the Hopkins Endurance 4-Way Flat Trailer Connector part # HM48110 and just connect the same color wires with item # DW05745-5 before you get to the connector.
