1969 Barracuda Dome Light Question

I recently got a rear wiring harness for my 1969 barracuda fastback. It has all needed wires except for the extension for the wires that run to the dome lights in the pillars. Does anyone know of anyone that makes a harness that plugs directly into this one and all I have to do is plug it in, put light bulbs in it and its ready to go? I am not able to find any and my old ones were cut and removed by previous owner so I'm not sure what the extensions look like. I added a picture of the connectors the cables need to plug into. Thanks in advance for help.
