IO4 – IO5/IO6 Radio Upgrade Conversion Harness

This harness is designed for those 2014 – 2016 – Silverado/Sierra Trucks, with an IO4 Radio (Factory OEM 4″ Screen); and wanting to upgrade to an IO5/IO6 Radio (Factory OEM 8″ Screen) along with a leather steering wheel, with radio/cluster controls.  With this harness, you will gain steering wheel/radio controls.  In addition, if you upgrade your instrument cluster to an appropriate instrument cluster, this harness will also allow you to control your cluster from your steering wheel.

NOTE:  This upgrade does require specific hardware – including an appropriate HMI, Radio Module, Radio Screen, and Instrument Cluster.  It also requires custom programming of these modules.  Custom programming is done by WAMS (www.WhiteAutoandMedia.com).  More information can be found here – https://www.whiteautoandmedia.com/product/4-inch-to-8-inch-upgrade-io4/

While WAMS performs the custom programming specifically for your truck/VIN, they can also supply the hardware.
