Right rear combination lamp not working

[Abiathar]

The passenger side combination lamp on my 2015 Ultimate has went out, none of the LEDs light up. I removed the trunk lid liner and checked the connection and did not see anything wrong. The wiring is identical for both sides so I removed the lamp assembly and tested using the working wiring and everything lights up correctly. Checked all fuses and they were fine, appears the BULamp fuse is for both lamps. I went through the service manual and could not find anything more than removal instructions. Does anyone have a wiring schematic or know of another harness or fuse for these lamps? I have not pulled the trunk apart get to check wiring.

Thanks,

Steve

Was able to get out and pull the trunk apart yesterday and found the issue. During open/close, the electrical tape had been work away and the ground wire for the lamp was cut. Crimped back together with a barrel splice, wrapped the exposed length in split loom to protect it, and it works normally now. Somewhere in that wire harness the backup camera has a loose connection and cuts out occasionally. Unfortunately, the care is just out of warranty and I'm having trouble finding where the break is as there are no other severed wires.
