What color are the neutral safety switch wires??

Ran into another electrical issue. Yesterday I put a radio in the dash, now the car wont start, not even a click. The headlights don't dim when turning the key, the battery is fully charged. The only thing I can figure is I must have accidently unhooked the neutral safety switch. So, what color are the wires for the neutral safety switch??
BTW, I ordered a service manual for the car but don't have it yet.
Where do the wires plug in??
67 Vista Cruiser.

The neutral safety switch is at the bottom of the steering column, near the firewall inside the passenger compartment. Here's a picture from the side on a 1967 Cutlass. It doesn't show up on the photo, but the purple wires also plug into the switch. John

We know you bought the Service Manual yesterday.

You really should wait until it arrives before attempting some of these projects.

It will make your life much easier.

Yep, I know. I have all the service manuals and parts books for my car, and a lot of times I go to them AFTER I can't figure it out......

Check the NSS, I bet that's your issue.

Try holding the shift lever all the way up in park against the stop.

Did you try starting in neutral as well as park? There is nothing around the radio that would impact the starter or the neutral safety switch. If you haven't moved the car since the radio install it's possible you leaned against the shift lever hard enough to move the linkage out of the "safety" range of the switch. Keep your foot on the brake pedal and move the shifter through its range of motion and see if the starter engages.

I got it, I had knocked the neutral safety switch loose. it apparently is loose, if I touch it wont start, have to wiggle it to get it back in place. Another task to do.

Old cars are not for wimps. They require attention just like most good things in life. The more time and love you put into it, the more enjoyment and satisfaction you will get out of it.

I got one of those big wiring diagrams and it is colored. I'm not in the shop but me thinks it's Classic Autowire. I put it in a frame. It goes on the wall, in a place where I can take it on and off to refer to it. This is the only way to go. It's big. And yes those wires are purple and they are purple in the console also. Go get 'em!!!

BTW: Petronix supplied info with their flame thrower coil that tells you to put two diodes in line from the coil to the tach. I got the correct ones, installed them and the tach(original Olds tach on the console) does work and it is accurate; verified by a laser tach off of the balancer.
