Please note this kit is for FACTORY 7 SPEED BLOWER MOTORS ONLY! If you have the factory 4 speed blower motor, you will need to purchase the kit we have available on the site for the factory 4 speeds to ensure you receive everything you need to get your radio and HVAC to work correctly. This kit will allow you to convert your factory RA1 or RA2 radios to the larger factory 8.4 RA3 or RA4 Radio. Included in this kit is the conversion harness needed for plug and play installation between the truck and the bezel and control module. You will keep all factory controls and will gain all factory controls through your new radio. The kit also includes the necessary control module you need for the factory 7 speed blower motor trucks for everything to work as it is supposed to. Not included in this kit are the bezel and radio. Control Module is a new Mopar module.
