7-Way to 4-Way and 5-Way Flat Trailer Adapter

Got this trailer light adapter that converts a 7-way round blade socket to a 4-way or 5-way flat plug. It's super handy if you have different trailers and dont want to mess with wiring every time. Has a little rubber cap to keep the gunk out of the pins when you aren't using it. Pretty much brand new, just sitting in the garage.
