I have a 2005 3500 with a RB4 radio. My steering wheel does not have the radio controls on the back side of the steering wheel. Can I just get a wheel that does and change it over? Is it already wired or do I need an additional wiring harness?

 

Chances are good that the pre wiring is there but I can't be sure. Try posting this thread in 3rd gen non drivetrain for a better response. Kurt
