Glove Box Light

My 74 Dart did not come with a glovebox light, however I found one on eBay. It is now in the glovebox, however the orange wire that is supposed to be tied in to the under dash wiring was cut when purchased. I have asked this question before, but nobody seems to be able to answer it.

WHERE DOES THE END OF THE ORANGE WIRE PLUG INTO THE WIRING HARNESS? Surely somebody can look under their dash and provide an answer. I have two plugs in the passenger side wiring harness with nothing plugged in to them. I think one of these may be for the glovebox light. Does anybody have a glovebox light?
