Yep - there are 2 sets of wires going through the '67 neutral switch. Purple/purple for the neutral safety and pink/bright green for the backup lights.
It very well could be the whole switch would be defective taking out both the backup lights and the neutral start feature. That's what I meant by 'check the switch' as in put the shifter in neutral and try and and start the car.
If it is the switch - I got a nice reproduction for the TH 400 from Rick's Camaros. My switch had been removed and the console wiring harness wires jumpered so the previous owner could start the car. So not only did I have to replace the switch, but the console harness too. Thanks, whoever you were!
