Step-by-Step Guide

Follow these steps to properly wire your tail lights:

Step 1: Remove Tail Light Assembly

The first step in wiring your tail lights is to remove the tail light assembly. You can do this by loosening the screws or bolts that hold the assembly in place. Carefully remove the assembly from the truck, and set it aside.

Step 2: Identify the Wires

Once you have removed the tail light assembly, you need to identify the wires. There should be three wires: black, white, and red. The black wire is the ground wire, the white wire is the running light wire, and the red wire is the brake light wire.

Step 3: Disconnect the Old Wires

Use your wire cutters to carefully cut the old wires. Make sure you cut close to the tail light assembly, so that you have enough wire to work with. Once the old wires are cut, you can dispose of them.

Step 4: Strip the Wires

Use your wire strippers to strip the ends of the wires. Make sure you strip enough wire so that you can easily connect the new wires.

Step 5: Connect the New Wires

Take your new wires and connect them to the tail light assembly. The black wire should be connected to the ground, the white wire should be connected to the running light, and the red wire should be connected to the brake light. Use your crimping tool to make a secure connection.

Step 6: Test the Tail Lights

Once you have connected the new wires, test the tail lights to make sure they are working properly. Turn on your truck and check that the running lights and brake lights are both functioning correctly.
