‘69 Dart Tail Light Issue. Yes, another one of these…

Nice car BTW.

Its easier to pull the dash out to check the wiring behind it. Have you check the harness from the drivers side kick panel all the way to the back tail lights? Like pulled seats, door plates, kick panel and just inspected it?
Thanks dano! I replaced the the engine front and the taillight harness already. It looked fine. I’m not sure what it takes to
Pull the entire dash out, but not looking forward to it…
