Step 1: Remove the OEM Tail Lights.
Use a screwdriver to safely separate the tail light from the chassis. Disconnect the stock harnesses from the tail lamp.
Step 2: Attach a Resistor Box to the LED Tail Light Assembly.
If you have a resistor box to prevent hyperflashing, attach it to the body of the LED turn signals and connect the wires.
Step 3: Connect the Wires to the LED Tail Light.
Once you connect the stock harness to the resistor box wires, test the tail light assembly to make sure it functions as intended. Once you've confirmed that it does, screw in the LED tail lights to finish up.
Your GMC Yukon is now equipped with an LED turn signal tail light set!
