You can find the Nissan 350Z LED Reverse Light/Rear Fog Light (72-003) here.
Step 1: First remove the bumper by removing the tail lights. There are 3 covers and you are going to pop it out with a flat tool exposing the fasteners underneath.
Step 2: Remove the bolts holding the tail lights and afterwards carefully remove the tail lights, unplug the tail lights, and set aside.
Step 3: After removing the tail lights you will find a 10mm fastener and remove that as well.
Step 4: There is a plastic retainer underneath the tail light that you must use a 8mm combination wrench and twist it 90 degrees in order to remove.
Step 5: If your Nissan 350z comes stock with mud flaps, you have to remove them as well. Unbolt the 2 screws holding it in place and carefully remove it. Inside the wheel well there are two, 10mm fasteners that must be taken out.
Step 6: Now that everything is loosened the whole bumper is only held on by clips. Gradually remove the bumper firmly, but gently. It helps if you have a friend to help you stabilize the motions as well.
Step 7: Remove the OEM bumper lights by the 2 screws holding it in place, and directly replace it with the new iJDMTOY LED bumper lights.
Now for the wiring portion:
Connect the LED turn signal/backup lamp assembly adapter to the stock harness.
Connect the LED turn signal/backup lamp assembly yellow and black wires to the load resistor. (Mount the resistor to metal, like the crash beam.)
Connect the blue and green wires to brake light and tail light.
Step 8: Now you can secure your Nissan 350Z LED Bumper lights in place.
Step 9: Check and make sure everything works and repeat the installation on the other side. Put back all of the components that you needed to remove for this installation, include the screws, clips, fasteners, and bumper. Test to make sure everything works and enjoy your new Nissan 350Z LED Brake Light/Tail Light/Reverse Light.
