Looking for the full wiring for both tail lights

[stephen major]

I bought a 15 Silverado and previous owners took out wire harness so now I am looking for complete harness that runs from the back straight to plug in

Where does the wiring harness that's missing start and end?

What I understood from this post you need these:

 

Driver Side Tail Lamp Wiring Harness - GM (23141278)

Passenger Side Tail Lamp Wiring Harness - GM (22869169)

 

These should be it but I'd call your dealer and verify part numbers with your VIN

From the cab to tail lights 

They supposed to be plugged in to those plugs

Those look like the plugs that plug into the Rear Lamp Wiring Harness Junction Block - GM (23208492). There shouldn't be plugs between the engine bay and the rear Jbox
