Adding back up lights

[Greasyfingers]

I want to add back up lights to my 64 dart wagon. I know it was an option. Did the factory run the wiring on all dart's and just add the switch and lights for an optioned car?

I'm trying to plan ahead in case I need to make or find a harness for them. I haven't had a chance to really check out the rear harness to see if anything is there.

On my 65 wagon the B/U light wire from the kick panel connector to the back to the rear was within the harness along with the connector even though there was no lights. I don’t remember if there was a b/u light switch or not

On the ones I had, the main wiring harness was the same, just no bulbs, sockets, pig tails, and lenses. On the switch, the push button auto's didn't have it, but, the manual trans cars did, but, no wiring to that switch.
