Hey everybody. If anyone can solve this one you'll be my hero for life. lol I have a 74 Roadrunner. The headlights and turn signals work fine in the front. But in the back I have no taillights and when you put on the turn signal either left or right both bulbs blink. Four-way flashers do work front and rear. And sometimes the reverse light yellow indicator below the dash will blink along with the turn signals. I have replaced all bulbs and both flashers. All fuses look good as well. Help!!!
 
Do you have a FSM? Get yourself acclimated with the wiring diagram in there and a multimeter. Sounds like you're missing a ground or something is shorting.
