What You'll Need

Before we start the installation process, it's important to gather all the necessary tools and materials. Here's a quick list:

  • Big Door Lamp for NPR (obviously!)
  • Screwdriver set (both Phillips and flathead, depending on your truck's setup)
  • Socket wrench set
  • Trim removal tool (this'll come in handy when you need to take off some panels)
  • Electrical tape
  • Wire connectors

Step 1: Preparation

First things first, make sure your truck is parked in a safe and well - lit area. You don't want to be fumbling around in the dark or on an uneven surface. Also, disconnect the battery to avoid any electrical shocks during the installation. It's a simple step, but it can save you a lot of trouble.

Step 2: Removing the Old Door Panel

To access the area where you'll install the Big Door Lamp, you'll need to remove the door panel. Use your trim removal tool to gently pry off any plastic clips or covers on the door. Then, use your screwdriver to remove the screws holding the panel in place. Be careful not to lose any of the screws or clips; you might need them later.

Once you've removed all the screws, carefully pull the door panel away from the door. There may be some electrical connectors attached to the panel, like for the power windows or locks. Disconnect these connectors by gently pressing the release tabs and pulling them apart.

Step 3: Locating the Installation Area

Now that the door panel is off, you need to find the perfect spot for your Big Door Lamp. Usually, there are pre - drilled holes or mounting points in the door where the lamp can be installed. Take a look at the instructions that came with your lamp to figure out the exact location.

If there aren't any pre - drilled holes, you may need to drill your own. But be extra careful when doing this. Measure twice and drill once! You don't want to mess up your truck's door.

Step 4: Installing the Lamp

Once you've located the installation area, it's time to put the Big Door Lamp in place. Line up the lamp with the holes or mounting points and use your socket wrench or screwdriver to secure it. Make sure it's tightly fastened so it doesn't rattle or come loose while you're driving.

Step 5: Wiring the Lamp

This is probably the most technical part of the installation. You'll need to connect the wires from the lamp to the truck's electrical system. First, identify the positive and negative wires on the lamp. Usually, the positive wire is red and the negative is black.

Find a suitable power source in the door. You can tap into the existing wiring for the door lights or power windows. Use your wire connectors to join the lamp wires to the truck's wires. Make sure the connections are secure and insulated with electrical tape. This will prevent any short circuits.

Step 6: Reinstalling the Door Panel

After you've successfully installed and wired the lamp, it's time to put the door panel back on. Reconnect all the electrical connectors that you disconnected earlier. Then, carefully place the door panel back on the door and press it firmly until you hear the plastic clips snap into place. Use your screwdriver to put the screws back in.

Step 7: Testing the Lamp

Once the door panel is back on, reconnect the battery. Now, open and close the door to see if the Big Door Lamp works. If it lights up, congratulations! You've successfully installed your lamp. If not, double - check your wiring connections and make sure everything is properly installed.
