Tail light issue please help
 

hello guys I'm have a few issues with my 2000 extended cab z71. The passenger tail light isn't working. Blinker, reverse light and brake light all work. I put a new bulb. I have replaced the wiring harness from the light to the rear circuit board. I replaced the circuit board as well and still nothing. From what I can find the fuses all look good to. Anyone have an idea what's going on?

thanks

Did the new harness include the socket that the bulb plugs into? make sure the new bulb is good.

Yes the harness has the socket to and the bulb is brand new after i installed the new harness
