How it Installation?

Step 1:

1.Open the hood, first disconnect the negative terminals of both power sources, locate the hood release rubber seal on the driver's side firewall, and then pull it out.
2.Locate the Engine Control Module (ECM), which is typically located in the front of the engine compartment on the driver's side, near the battery. First, remove the bracket from the ECM, then disconnect the first ECM closest to the cab from its connector.

Step 2:

1.Carefully thread the wire through the hole where the rubber gasket was removed earlier into the engine compartment from the cab. Ensure the wire on the engine compartment side is long enough to connect to the Engine Control Module (ECM) harness.
2.Use the conduit provided with the switch to protect the switch wire from high temperatures. Carefully reinstall the hood latch rubber gasket around the harness.

Step 6:

This step only applies to 2011 model trucks. Use a pry bar or paperclip to insert between the pin and the device gap of pin #11 to pop out the yellow pin of pin #11.

Step 7:

1.Insert the yellow wire into pin #11 and the black wire into pin #35, ensuring they are fully inserted into the bottom of the ECM connector.
2.Install the panel with multiple pinholes on the connector insertion side and the ECM harness cover.

Step 8:

1.Finally, reconnect the ECM connectors to the ECM. The engine compartment installation is now complete.
2.Drill a small hole of appropriate size on a suitable panel near the dashboard in the driver's cab and install the switch.
3.Secure the switch harness to the other harnesses below the dashboard using electrical tape or cable ties.

DESCRIPTION

Product Overview

Unlock the true potential and versatility of your 2006–2010 GM Duramax LBZ or LMM engine. The TruckTok 5-Position SOTF Switch lets you change your truck's power levels instantly from inside the cab—no more pulling over to reflash computer or waiting for a programmer to load.
Whether you need maximum fuel efficiency for a road trip, extra torque for heavy towing, or full horsepower for the track, this premium rotary switch delivers crisp, on-the-go mapping adjustments in less than a second.

Key Features

Billet Aluminum Knob: Features a high-quality knurled aluminum knob that offers a rugged grip and adds a sleek, professional look to your dashboard.
Engine Bay Protection Ready: The entire wiring harness is wrapped in a high-temperature split loom to protect the delicate signal wires from engine heat, vibration, and friction.
Instant Map Switching: Seamlessly toggle between your 5 custom-tuned profiles (such as Optimized Stock, Eco, Heavy Tow, Street, and Race) without shutting down the engine.
Pre-Terminated Factory Pins: Engineered for a clean installation. The wires come with factory-style pins that slide directly into your specific LBZ or LMM ECM connector—no slicing or wire cutting required.

FAQ

Q: What happens if the switch gets unplugged or a wire breaks?

A: The ECM will default to Tune 1. The switch works by changing electrical resistance; if the circuit is broken, the ECM senses maximum resistance and automatically reverts to first tune slot (usually base or stock) to ensure safe operation.

Q: Is the switch harness waterproof? What happens when I wash my engine bay?

A: Avoid blasting high-pressure water directly at the ECM connectors when washing the engine bay. Ensure factory rubber seals are fully seated to prevent moisture from causing voltage fluctuations between maps.

Q: Is there a delay when I click the switch to a different power level?

A: The change happens instantly, in less than a second. The moment you click the knob, the ECM immediately switches fuel and timing maps, though your turbo may take a brief moment to spool to the new target boost.
