back-up lights on 64 dart gt

Thank you 67Dart273 that diagram helped greatly!! I found the switch on the shift control and removed it. I could not get power through that switch, so my wife and I tried to fix it ( the price on a new one was $89.00 on EBAY), but alas it could not be re-built. I did however find another one for a 1961 desoto that will work, so I ordered that one! Thanks again.
