Product Description
EDGE PRODUCTS 98650 EAS SOTF – SHIFT-ON-THE-FLY CONTROL FOR 2011–2014 FORD 6.7L POWER STROKE
The EDGE PRODUCTS 98650 EAS SOTF (Shift-On-The-Fly) Accessory lets you change custom tunes on the fly right from your Edge Insight monitor instead of using a separate dash-mounted switch. Designed specifically for 2011–2014 Ford F-250/F-350 6.7L Power Stroke trucks running SOTF/DST-style custom tuning, this plug-in accessory gives you clean, on-screen power level control without drilling holes in your dash.
- Integrates with Edge Insight CS2/CTS2/CTS3 monitors for on-screen tune changes*
- Replaces traditional 5-position SOTF/DST rotary switches
- Uses 1–5V outputs to cycle between custom tune levels**
- Clean, factory-style install – no extra holes in the dash
- Perfect for EFILive, EZ Lynk, and similar voltage-based SOTF custom tuning
*Insight monitor required (sold separately).
**Requires custom tuning that supports voltage-based SOTF/DST switching.
FITMENT – 98650 EAS SOTF (SHIFT-ON-THE-FLY)
- Engine: 6.7L Power Stroke V8 diesel
- Vehicle: Ford F-250 & F-350 Super Duty
- Model Years: 2011, 2012, 2013, 2014
- Drivetrain: Compatible with 2WD & 4WD

This accessory is built for 2011–2014 Ford 6.7L Power Stroke applications and must be used with custom tuning that utilizes a 1–5V signal for switch-on-the-fly power level selection.
HOW THE EDGE 98650 EAS SOTF WORKS
Instead of wiring in a separate mechanical SOTF or DST switch, the 98650 EAS SOTF uses your Edge Insight to output five distinct voltage levels (1–5 volts). These voltages are read by your ECM or auxiliary harness in the same way as a traditional SOTF switch, letting your custom tune select between multiple power levels while driving.
- Install the EAS SOTF accessory inline with your Edge Insight harness.
- Wire or plug the output into the same circuit your tuner expects for SOTF/DST switching.
- Load custom tunes that support voltage-based SOTF/DST control (EFILive, EZ Lynk, etc.).
- Select power levels right on the Insight screen as you drive.
Important: This product does not include or add tuning by itself. It does not convert an Insight monitor into a programmer or downloader; it simply provides an on-screen interface to control existing custom SOTF/DST tunes.
KEY FEATURES & BENEFITS
- On-Screen Power Levels: Change tune levels using your Insight CS2/CTS2/CTS3 monitor—no extra switch on the dash.
- Clean Interior Install: Avoid drilling holes or cutting trim for SOTF knobs or rocker switches.
- Built for Custom Tuning: Ideal when your tuner supports voltage-based SOTF/DST (EFILive, EZ Lynk, and similar platforms).
- Edge EAS Integration: Works within Edge’s expandable accessory system (EAS) for a tidy wiring layout.
- Quality Construction: Backed by Edge’s limited warranty and designed for harsh diesel environments.

FAQ
Does the EDGE 98650 add tuning to my truck by itself?
No. The 98650 EAS SOTF accessory does not add power or load tunes on its own. It simply gives you on-screen control of existing custom SOTF/DST tunes through an Edge Insight monitor.
Which monitors will work with the 98650 EAS SOTF?
The 98650 is designed to integrate with Edge Insight CS2, CTS2, and CTS3 monitors using the EAS (Expandable Accessory System) harness. Confirm monitor compatibility and firmware with Edge before ordering if you’re unsure.
Do I still need a separate SOTF switch?
In most setups you will not. The purpose of the 98650 is to replace a physical 5-position SOTF/DST switch and instead use the Insight screen to command the same voltage steps the ECM or harness is expecting.
Will this work with stock factory tuning?
No. The 98650 is intended for trucks running custom tunes that are specifically configured for voltage-based SOTF/DST switching. If your truck is stock, you will not gain any benefit until you add compatible custom tuning.
Is this product emissions compliant for on-road use?
Emissions legality depends on your custom tuning and local regulations. The 98650 itself is an accessory, but many custom tunes are for competition/off-road use only. Always review your tuner’s emissions notes and obey all federal, state, and local laws.
