Step-by-Step Wiring Guide

Follow these steps to wire your 3 wire LED tail lights:

Step 1: Disconnect Battery

Before you start working on your vehicle’s electrical system, make sure to disconnect the battery to prevent electrical shock or damage to your vehicle’s electronic components.

Step 2: Remove Old Tail Lights

Remove the old tail lights from your vehicle by unscrewing them or using a pry tool to gently pop them out of their housing.

Step 3: Install LED Tail Lights

Install the 3 wire LED tail lights in the same location as your old tail lights. Secure them with screws or use the provided clips to snap them into place.

Step 4: Connect Wires

Using a wire stripper, strip a small section of insulation from the end of the wires on your new LED tail lights. Use wire crimpers to attach butt connectors to the exposed wires.

Match the colors of the wires from your vehicle to the wires on your LED tail lights:

  • Black wire – Ground (-)
  • Red wire – Brake Light (+)
  • White wire – Running Light (+)

Connect the black wire on your LED tail lights to a metal grounding point near the tail light assembly. Connect the red wire to your vehicle’s brake light switch and the white wire to the running light circuit.

Step 5: Test Lights

Reconnect the battery and turn on your vehicle’s headlights to test your new LED tail lights. If they’re not working, check your connections and make sure everything is properly grounded.
