‘68 Dart, One tail light not working.

Update.. well I think I have something … some shoddy wiring.. leads me to believe it needs a new headlight switch. I wasn’t getting power going into the turn signal switch for the driver side rear.. if I’m following the schematic right, headlight switch feeds it… pulled the plug on the headlight switch and I find this. The wires on the exit look good, plug itself looks good… best guess is the headlight switch needs to be replaced since one end of that jumper wire goes to the wiring to the left rear tail. Sounds logical anyhow.. I can’t imagine this is factory :lol:

I have not looked into the plug, but in 68 the park lights still went off when you turned the headlights on. If you want both you can run a jumper wire on the switch to make them stay on.
