Question: Passenger side tail light and passenger side rear marker light do not work

Brake light does work. Bulbs are new and have been tested so are known to be functional. however, tail light does not illuminate (other side does) and marker light will not illuminate either. Suspect short or broken wire in the circuit prior to the split to each fixture.

Where are the likely spots to look for a break or short in the wiring harness?

As a side note, make double sure the bulbs you put in are the correct number bulb, as incorrect bulbs can cause this problem.
