I've just done a bunch of research on my 05 as I am adding an OEM locker switch into my non-Rubicon. If it helps you, here's all the different part numbers for an 05 dash harnesses. I was able to get a 56047312AB (from a Rubicon w/ Hard Top) harness on Ebay for $130 shipped.
GNN = Auto Dim Mirror W/Lamps/Compass/Temp
VJO = Soft Top
VKO = Hard Top
DSE = Rubicon
77 = Short wheel base
78 = Unlimited (long wheel base)
DG0 = All Auto Trans
DBB = All Manual Trans
