Divorced choke resistor

'74 Dart, 225 /6, A904. Sorry for the noob question but this is my first Dodge, first slant six and first divorced choke. Just put a "new" Holley 1945 on her and would like to make sure the choke is working properly. PO had a Holley 1920 on it and the choke rod from the manifold would not fit so he left it loose. Hooked up the choke rod to the 1945. Fast idle kicks in appropriately but the choke does not back off when warmed up. Inspecting everything I notice a wire disconnected at the resistor(?) and showing cracked insulation. First off, is the vacant terminal (labeled choke control) I have on the resistor where the loose wire should be plugged in? Should it be hot in "run" only? What resistance should I be reading hot or cold? Is the resistor assembly still available out there somewhere, mine looks pretty sad. Any and all help will be greatly appreciated!
