The ebay ad for these updated taillights says the connection is behind the bumper. Why not in the cavity from where the light is removed?
Chief I couldn't find the pics, can I see too? I'm doing a total chrome delete.The connection is behind the bumper, you have to lay on the ground to unhook them.
I got the smoked ones because the truck is black.
I used these: Smoked LED Tail Lights for Cadillac Escalade / ESV 2007-2014 Assembly Rear Lamp | eBay
Here is the long 3rd brake light I used: Long Version Smoke LED 3rd Brake Lights Bar for 2007-2013 Suburban Tahoe Yukon | eBay
There is a picture of them installed on the Limo page you started.
