！Before installation, confirm that：
This high-performance component does not comply with the laws and regulations for highway driving and cannot be used on any vehicle that has been registered or certified for use on highways. This means that the component may only be suitable for racing cars or other off-road vehicles. If it is installed on vehicles driving on the highway, legal issues will be borne by oneself.
This is the installation process for the ER-0296: 2011-2016 Chevy Duramax LML 5 Position Switch,provided for your reference during installation.
Step 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.
Step 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 3:
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.
Step 4:
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 5:
Remove the cover from the ECM harness that was removed in step 2.
Step 6:
Remove the panel with many pinholes on the side where the connector is inserted.
Step 7:
Locate pins #11 and #35 of the ECM.
Step 8:
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 9:
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.
Step 10:
Install the panel with multiple pinholes on the connector insertion side and the ECM harness cover.
Step 11:
Finally, reconnect the ECM connectors to the ECM. The engine compartment installation is now complete.
Step 12:
Turn the ignition switch to the "ON" position. Press the small white test button on the back of the switch. If one of the LEDs lights up, the pins are in the correct position. If none of the LEDs light up, check the wiring connections.
Step 13:
Drill a small hole of appropriate size on a suitable panel near the dashboard in the driver's cab and install the switch.
Step 14:
Secure the switch harness to the other harnesses below the dashboard using electrical tape or cable ties.
