99 Toyota Tacoma sr5 tail lights not working

I have a 99 Toyota Tacoma sr5 ext cab 4cyl auto, the turn signal breaks and head lifts all work no trailer brakes head lights work but no tail lights bulbs are good relay is good. I have power at the fuse box but none at the connector beside driver seat so the problem is somewhere between there I just don't know where to look next. Please advise

 

Short question is Everything works with the exception of the Tail Lights?

Did you check the Tail Light Fuse? It should be labelled as " Tail ".

 

Yes fuse is good. No power at the plug beside the driver seat
