2-Speed Wiper Motor Question

I took the 2-speed wiper motor out of my 69 Dart years ago when I tore the car apart to restore it. I am finally to the point where I am reinstalling it. The problem I've encountered is I don't know what I did with the ballast resistor that mounts to it. I am sure I bagged and labeled it but I cannot find it. All I can find is a box of miscellaneous ballast resistors I have collected over the years. Is the wiper ballast the same as ignition resistors and if not, is there a way to tell the difference by either appearance or testing? Also, the bulkhead harness that has the plug that goes on the wiper motor also has a long brown wire with a black plastic covered connector on the end. I don't remember for sure but does that wire connect to the starter relay?
