2018 Tundra wiring help mouse damage

I have a 2018 Tundra Extended cab. I noticed my 3rd brake light a bed lights quit a couple weeks ago. Fuses ok, bulbs just no voltage to these items.

I found had a couple mice in my truck, set up a trap line and caught them. I suspect like most of these critters do they chew on stuff including wires. And these wires got cut.

Any idea where Toyota would route these wires thru the cab to the top of the cab behind the rear seat?

Tried goggle not much help

 

You access the 3rd Brake Light at the rear of your ceiling liner. Do a GOOGLE search for Tundra 3rd Brake Light Install. A guy posted a very good video of what to remove to access the wires.
