Classic/Antique Car Repair: 1966 Mustang Pony replace back up light switch, automatic transmisson, neutral safety switch

Question
Hello Brad, Dale here. I am restoring a 1966 Mustang Pony, with automatic transmisson mounted on floor (console). Need to replace the back up light switch. However all the books I have do not indicate location of such. Can you provide me with such information and proceedure? I hope so.

Answer
The back up light switch is part of the neutral safety switch and is bolted to the side of the transmission where the kick down linkage attaches to the transmission. The switch can be adjusted. With the shifter in Park insert a small drill, size 43, through the hole in the switch. Loosen the bolts holding the switch to the transmission case and rotate the switch until the drill goes all the way through. Then tighten the bolts.
