Thanks for the mention Daniel.
@Ahoward , no one, I mean no one offers an HVAC conversion harness to go from the 8.4 system down to the 5" MTC system (4 or 7 speed). ... It would be a pain in the A$& and not worth the effort.
Not sure what aftermarket radio you're running there, (can't tell from the picture) but if it's a double din unit, you can get an idatalink Maestro or PAC Radio Pro bezel interface kit to integrate it.
If that's some sort of Android Tablet radio built into a Bezel, specifically for a 4 speed 5" radio truck... You're likely out of luck unless they can send you a different interface harness for it (some of the T-Style radios do this I've heard. .. But they still don't integrate well).
Found it here... Not a good match for your truck
