Back-up lamp switch, will it work when 3-speed column is rigged for automatic???????

[SWINGSAX68]

I am having a hard time finding an Automatic column for my 68.

So......we are just rigging up the already there 3-speed column, will the back-up lamps work if switched to the right place with the shifter??

If not,what can I do to make them work with the shifter.

OR....how do I add a switch for the back up lamps that will be neatly placed where the Choke knob was.
