Good evening. I have a 2020 GMC 1500 Denali, with all technology options and it has the jacks on the back for the additional cameras. I have been trying to purchase the Camera package that will allow me t do te invisible trailer view. Unfortunately, I cannot find anyway to order the part for the camera package. I found this part Trailer Auxiliary Camera (Models W/Trailer - GM (84876818) but that is on backorder indefinitely. Does anyone know where I could purchase these camera's and harness? Is this something I can part together? Any help would be greatly appreciated,
