Passenger tail light not working help....

New harness from rear shackle back new bulbs new tail lights all lights function as should but my passenger tail light is the only light not working I have power at the driver side jumper connector but also noticed my passenger side licsence plate light is not working tried swapping bulbs to to driver side bulbs work in desperate need of help with this if anyone has any input please also checked fuses put all new fuses in too

 

So the brakelight works on pass. side? And blinker? if not it's prob. ground. Power at bulb base?

 

Yes brake light works turn work and reverse all work just not tail light im not the best at electrical stuff so if there are any grounds in the rear idk where it be located to check

 

Use the test light (or any 12V light) to check the bulb sockets for power. You'll get the hang of it. The shell of the socket is grounded, The lead poles IN the socket should supply power.

 

I'll check when I get back home but just a ? If my brake light is working but not tail light the socket should be getting power rite? Or no?
