Fish Tuning FTFord2008-2010 5-Position SOTF Switch – 2008-2010 Ford 6.4L Powerstroke (White/White) for EZ Lynk & SCT

Upgrade your 2008-2010 Ford 6.4L Powerstroke with this plug-and-play Shift-On-The-Fly (SOTF) switch from Fish Tuning. Designed specifically for the unique double-white-wire fuel temperature sensor connector on these trucks, the FTFord2008-2010 lets you instantly switch between up to five preloaded tune levels while driving—no laptop, handheld reflash, or stopping required.

Key Features

• True plug-and-play design that connects directly to the factory fuel temperature sensor harness (white/white wires)
• 5-position rotary switch for seamless on-the-fly power level changes
• Durable aluminum knurled knob with clear 1-5 position decal
• Includes Allen wrench and split loom tubing for a clean installation
• Works with EZ Lynk, SCT, BDX, and other compatible SOTF-enabled tuning platforms

Fitment

• 2008, 2009, and 2010 Ford Super Duty trucks equipped with the 6.4L Powerstroke diesel (F-250, F-350, and related models)

Important Notes This switch does not contain or load any tunes. Your ECM must already be flashed with SOTF-compatible calibrations (multiple power levels) from your tuner before the switch will function. It simply varies resistance in the fuel temperature sensor circuit so your tuner can select the corresponding map.

Perfect for drivers who want convenient, real-time control over tow, street, and performance tunes without the hassle of traditional programmers. Simple, reliable, and purpose-built for the 6.4L platform.
