Tazer 13-21 RAM 1500 Classic/2500/3500 Tazer RAM Programmer
The Tazer RAM is a plug-in device to change vehicle settings and provide some extra functions that were not available from the factory. It works on all engine variations, including the diesel. Needs to have the speedometer cluster that has the ability to display radio station information - only the older base model trucks may have the cluster that does not. All color displays will work.
