I am the point in my build where I need to hook up the neutral safety switch/backup lights.
I bought the car without a motor or transmission. I have installed a motor & transmission and aftermarket shifter.
I am at the point where I need backup lights and getting the car to start with the key.
There is no neutral safety switch, currently on the car and I can not locate any wiring that goes down to that switch. The pervious owner may have cut it out, when removing original motor/transmission. Could someone please help me with this issue?
Need to know where the wiring for NSS/Backup Lights starts at and if there is a part or wiring system I can purchase to make this right and work correctly?
Pictures would be great.

Thank you.

The '68 neutral safety switch screws into the side of the transmission case just above the shift lever. It is a single pole switch. A wire runs from the single terminal to the starter relay to supply a ground to activate the relay.

If I remember correctly, the backup light switch is on the top of the steering column down by the brake light switch inside of the car. There is a tab that sticks out of the column and inserts into the switch to move it and energize the backup lights. If you have an after market shifter, there usually is no provision for a backup light installation on the shifter, so you will need to improvise.

Since I am not using the factory column shifter, how would I be able to get the backup lights to work, with a floor shifter? Again thank you

You could use a toggle switch mounted on a bracket under the dash if manual operation is all you want. If you installed a '70 or later transmission, it will already have the 3 pole switch to activate the backup lights. On a'68 transmission, you would need to change to the later rooster comb inside of the transmission. Then you can install the 3 pole switch. The two outer terminals on the three pole switch complete the circuit to the backup lights. If you do not want to go to that much trouble, you might be able to fabricate a bracket on you after market shifter to accommodate a switch for the backup lights. If this was my car, I would probably stay with a column switch with the factory linkage.
