Need help debugging my rear lighting issues

[Moparfiend]

Need help debugging my rear lighting for my 1970 Plymouth Satellite.

Symptoms:
Rear tail lights:
Driver side…………Passenger side
Running lights OK. Running lights OK
Brake lights OK. No brake lights
Turn signal OK. No Turn signal
No emergency flasher. No emergency flasher
No reverse lights
License plate light works
Front signals ok also emergency flashers.

All new bulbs and sockets in rear
Instrument signal lights work
New turn signal switch (untested until now).

I took the steering wheel off and inspected the switch. Horn sometimes goes off with turn signal switch. Looking at this now.

So I just checked the body connector and sure enough similar issues persists the there. It must be a harness issue right?

It appears that the turn signal switch surprisingly is showing all the hazard and turn flashing. This is pointing to the harness between the switch and the body connector somewhere.

Just updating this thread. I got everything working except the rear hazards. The front hazards work so it’s not the switch. I have signal down to the body connector un-plugged. So the issue is in the rear harness but I have turn signals and brakes and running lights in the rear. Kinda strange.

Probably a grounding issue with the lights.

The weird thing here is, if you got brakes you should get hazzards since wiring is the same for both.

The issue is, hazzard contact is not getting the rears into the switch itself.

Confirmed just now new turn signal switch was bad. I didn’t want to blame any parts as I rebuilt my entire harness and it was possible I made a wiring error. But indeed bad switch!

In troubleshooting the wiring of the steering column and turnsignal switch, I found this article to be helpful..
Just my $0.02...

Those yellow cammed turn signal switches are not good quality. It is well worth the money to find an oem switch.

Yeah in researching this I read your past post showing where yours cracked.

I got mine from Rick Ehrenberg. He said these particular switches are made by an OEM and he sells good stuff from my past experience.

Old OEM switches may be correct but if plastic breakage is an issue, 60 year old plastic will not be very good and these switches flex a lot. So I am not convinced paying $150 for old plastic is a good value.
