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

I chased electrical gremlins for a long time on mine. If I had it to do over again I would buy all new M&H harnesses from year one and change it all out.

Do the taillights work if you swap the LED bulbs back in? Looking for clues…..modified wiring is hard to troubleshoot.
Hey Mike, I haven’t tried putting the LED lights back in since they didn’t work originally. The only wiring that wasn’t replace back to factory.. or reproduction factory was under the dash. I’ll put them back in and see if anything happens again..
