I'm putting a Matt McKee Iron Man topper on an Iron Man vault edition. It used to be installed on an older Iron Man. I assume it is 12V, it has a three hole connector with two wires, one red and one black. I'm not finding a factory connector in my Iron Man vault that matches the connector. Does anyone know the best attachment point for this or do I have to fabricate some sort of splitter connector? I don't have the original instruction sheet. Thanks in advance.
