Adding Rear screens to an 11 Suburban LS

[flynn78us]

So this is my 4th version of these lovely vehicle and my first with no RsE. I had an 07 Avalanche LT3, and 08 Tahoe LTZ, a 10 75th Annv Burb, and now my 11 LS. I wanted the 9 passenger and figured the wiring was in The overhead probably for rear Ent.

anyway I’m to my quest. I’d like to add second row
Minimum possible third row if I can. I would need to know and see how people moved the rear heat/air controls and what others have done adding RSE to a low optioned LS
