Are they on the same fuse as the turn signals?
Yes.

Op, did you check for voltage on the purple wire and the turn signal connector? A test light would work fine. No, I did not realize its a manual transmission car until you mentioned it.

On a 1969 Chevelle, the turn signals, back-up lamps and “IGN” add-on port on the fuse block are all controlled by the single 20 amp fuse labeled “DIR SIG BACK UP”.

If this fuse is blown or the clips holding the fuse have excessive corrosion causing an excessive voltage drop, you will have no turn signals or back-up lights.

I will check the purple wire and the turn signal connector tomorrow and see what I get. I will also pull the 20 amp fuse and look for corrosion on the connectors although the fuse panel looks pretty clean.
The car was originally an automatic. Someone must have jumpered the wires to the neutral safety switch since the car will start even though there are no wires connected to the neutral safety switch on the column . Thanks Coppertop for the info. Good to know. Back at it tomorrow.

Ok, the purple wire has 12 volts at the connector to the steering column and checked the fuse holder for any corrosion and it is clean. I guess this may point to the switch for the turn signals. i cannot see the pink and green wires that were on the neutral safety switch.
I guess I will need to drop the steering wheel and pull the dash to see everything in there.

I think the pink and light green are for the reverse lights. Those should be in a connector that is at the base of the steering column. As a matter of fact you will need to find those to make your reverse lights work with a 4 speed (assume this is a Hurst Competition) and this https://www.jegs.com/i/Hurst/530/2480003/10002/-1.
Which mounts to the rear stop on the shifter housing. Need to run one wire to the pink from the switch and one wire to the green from the switch.
If you just jump the pink to the green the reverse lights should come on.

I'm thinking your directional switch went south because there is voltage at the connector. You don't need to remove the dash to see whats going on. The original NSS switch is on the column and the wiring should be close to it.

BLM - Thanks for the information on the back up light switch. I will be working with that later on. It is a Hurst shifter.
oldcutass- Yeah I am thinking it is the switch also. I have done some research on that and sounds like you need to replace the switch and run the wires down through the column. Thanks for the help. RichF
