Show original supplier description
The Spelab DSP5 SOTF Switch is a performance upgrade designed for 2011-2016 LML 6.6L Duramax trucks equipped with EFI Live DSP5 tuning. This switch enables you to seamlessly toggle between up to five custom-tuned programs directly from the cabin, eliminating the need for OBD2 reflashing. Its premium construction includes a durable, knurled aluminum knob for enhanced grip and high-temperature wiring with split loom protection to withstand demanding engine bay conditions. The driver-centric design allows for convenient mounting in various interior locations such as the dashboard, switch panel, or center console. A critical note is that your vehicle must already be preloaded with a compatible EFI Live DSP5 tune or EZ LYNK that supports multiple maps for this switch to function. Installation locations include the dashboard, switch panel, or center console. Wiring connections involve connecting the yellow wire to ECM Pin 11 and the black wire to ECM Pin 35, routing the wires through the driver-side firewall grommet. The switch supports various modes, including Economy, Light Tow, Heavy Tow, Performance, and Race, catering to different driving and load conditions. This product is intended for off-road use only. Professional installation is recommended for those less familiar with vehicle electronics.
