The RA4 has a bezel with the controls. That's what I am attempting to use. The problem is an incompatible climate control plug. That's the physical holdup. I don't know about any BCM limitations yet. I'm waiting to see what jeepguy_1980 has to say.

Is there anyway you can compare wiring at the plugs via a schematic? That will at least give you an idea what's missing at each plug. If the wiring is essentially the same, minus the plug being different, you might get lucky.

the wiring might actually be the easy part.. its getting the bcm re-programmed that will be the tough thing. alot of dealers dont even know how to turn on sales codes (ex back-up cam). let along to do something more in depth like this.

OP whats your objective in the project? have you thought about a nice aftermarket double din? an aftermarket radio will sound 10x better and will also have more functions available.

I have no desire for aftermarket. I have had way too many aftermarket thefts in my day. No one wants to steal stock radios. Aside from that, I think many aftermarket touch screen units have cheesy looking interfaces.

It did not come from the factory. I had it dealer installed as part of the deal. I was told it would be in the rear view mirror but when I got the truck they had enabled it in the head unit. So, yes it does now.

After some more probing around on the tech authority site I noticed a difference between my VIN and the VIN that the 8.4 was salvaged from. Under HVAC SYSTEM - MTC the 8.4 VIN has a second A/C Heater module labeled C2. This may or may not be important... the search continues.
