Pac CH1A-RSX Radio Installation Adapter for Chrysler Dodge Jeep RAM Vehicles with CAN-Bus System - Perfect for Aftermarket Stereo Upgrades in Trucks & SUVs

It didn't match up with existing wiring in my 2008 Dodge RAM and wasn't able to use it. The instructions were not clear on hooking it up. The price was extreme for what you get and didn't even work for my application. I did send it back and received a full refund, so nothing lost but time.
