1971 Dodge Dart Swinger Turn Signals and Reverse Lamps
If the engine bay back up connector NSS is unplugged, then the back up lights will never work.
Could that effect the turn signal?
The answer is no.
The branches can be disconnected and the main line will still carry power.
Conversely, the radio and backup lights can be on, and the turn signals will still work.
More electrons are needed, but the supply wires are big enough to carry to carry the current to all of them at the same time.
But if a branch wire is touching ground, or any other wire with less resistance to ground, the electrons will take the easy path to ground and completely avoid the more difficult route.
Since there are turn signal issues along with a reverse light problems, if disconnecting the reverse lights solves the problem, then there is probably a short in the back up light circuit. Just like this guy found (see post 87)
