2004.5-2005 LLY DURAMAX | DIGITAL SWITCH
We took our small rotary switch and supersized it. Now with the Digital switch you have the ability to shift your tunes on the fly with a nice LED lit Gauge, instead of a little knob. They come in multiple colors (blue, red, green, & white) so you can pick what best suites your truck. Install and setup is quite simple, only a few wires to run and minimal tools needed. Available with High-Idle function as well.
