reverse light wiring question

I have 65 Dart i'm in the process of restoring. My car didn't come with reverse lights from the factory but I know there was a kit made for this. Anybody know what this entails? I'm guessing a switch/solenoid at the transmission and a little wiring to the tail end. Can't be much more than that, right?
Its a slant 6/904 car if that helps any.
