3. Prepare the Mounting Surface:
   • This is the most critical step for strong adhesion.
   • Thoroughly clean the mounting surface with rubbing alcohol or a specialized surface cleaner. Remove all dirt, grease, wax, and debris.
   • Allow the surface to dry completely. For optimal adhesion, the surface temperature should be above 60°F (15°C).
4. Wiring the Strips:
   • Identify a Power Source: For most installations, you’ll tap into a 12V DC power source. Common options include:
     • Accessory Fuse: Use a fuse tap in your truck’s fuse box to get switched power (power only when the ignition is on).
     • Direct to Battery (with switch): For constant power, run a fused wire directly from the battery to a dedicated switch in the cabin.
     • Existing Lights: For tailgate bars, you’ll tap into your truck’s existing tail light, brake light, and turn signal wires.
   • Connect Wires:
     • Connect the positive (+) wire from the LED strip (usually red) to your chosen 12V power source.
     • Connect the negative (-) wire (usually black) to a good chassis ground point on your truck.
     • If using a controller, connect the LED strip to the controller, and then the controller to the power source.
   • Install Fuse Protection: Always install an in-line fuse as close to the power source as possible. This protects your truck’s electrical system and the LED lights from power surges.
   • Secure Connections: Use high-quality crimp connectors, solder, and heat shrink tubing to ensure secure, waterproof connections. Avoid simple twisting and taping for exterior applications.
5. Mounting the LED Strips:
   • Once the surface is clean and dry, peel off the adhesive backing from a small section of the LED strip.
   • Carefully align the strip and press it firmly onto the surface, working your way down the length of the strip, peeling more backing as you go.
   • Apply firm, consistent pressure for at least 30 seconds to ensure good adhesion.
   • For added security, especially in high-vibration areas or on rough surfaces, use the included mounting clips or small screws (if provided and appropriate for the surface).
6. Test the Lights:
   • Before tidying up all the wiring, turn on your truck and test the LED lights to ensure everything is working correctly (colors, patterns, functions).
7. Secure and Tidy Wiring:
   • Route all wires neatly and securely using zip ties and wire loom.
   • Ensure wires are tucked away from hot engine components, exhaust, moving suspension parts, and sharp edges.
   • Seal any exposed connections with silicone sealant or liquid electrical tape for extra weather protection.
