Tail Light Harness has different ends

[Lanaue]

So my new to me 07 Z71 came with aftermarket taillights and the passenger brake and park lights don't work. It has the Cadillac Escalade tail lights. So the right side has an 8 pin socket and the left has a 6 pin socket. Is that normal ? I looked at a few videos and one of the trucks had 6 pin sockets on both sides. I couldn't tell on the other videos.

ya the cadillac harness is different I believe one side carries the wire for the center brake or something to that effect if you search the forum a bit you can find some diagrams to make it work or there may be some one still selling a adapter
