What's this for?

Dana, quick question.... I cosmetically restored a 70 Duster rally dash and im going to put it in my 73 non rally dash Duster. The round flasher is present on the rally dash near the ash tray area and im guessing the signal stat would go in the square holder on the bracing where the steering column bolts up...im having trouble finding where the signal stat would get its power. There is one connector that isnt hooked up to any thing thats in the general area so that might be it, its a "T" shaped connector with 2 wires. One wire is white and one is black... i hope im making sense....any ideas...Rich
