Use this setting when driving on hard-packed sand, ice or snow covered roads, and dirt roads. 4L is best suited for a time when you need and power. Use 4L when driving in deep mud or snow, soft sand, up steep inclines, and on extremely rocky surfaces. Stick to low speeds in this setting, around 10 MPH. Installation: Gently pull out the front part, remove the screws together and you'll see the back end. Pry three small holes with a small flat-head screwdriver, then pull out the switch and you should see a connected harness. Unplug the harness from the old switch. Connect the new switch to the wire harness and press in (note: insert the switch after alignment to avoid deflection when the buckle is wrong). Package:1 x Control Switch Knob
