09 Passenger Tail Lamp Issues

Having problem with passenger tail lamp that will not stay on.  Brake lights, backup, and turn signal still work.  Checked fuses on side of dash and under hood and swapped tail light assembly with drivers side so everything  appears to be working fine.  Dropped spare tire to trace harness and couldn't find any junction blocks like earlier body styles that I've read about here by the wheel wells.  Harness appears to connect into larger harness and run along drivers side forward to fuse area. 

Does anyone have a wiring diagram or can confirm there is no junction block similar to older body styles?

Thanks in advance!

The newer av don't have the junction block, just the pigtails harness.

Thanks for the junction box info!  I continued to test the harness that holds the bulbs in place.  Shaking the harness causes the running lights to come on intermittently.  Performed continuity check at each socket in the harness and getting some resistance on ground line too.  Ordered a new harness from the dealer and installing it tomorrow.
