What up fam, This is a video of my installing the ijdm 4th brake light onto the 370z. I needed to fill in the hole for the diffuser so this completed the look. ijdm toy 4th brake light www.amazon.com/dp/B00V427GPK/...
The 350z doesnt have a hole to mount the light unless you make an aftermarket one. If you wire it to the correct wires not sure if they are different from the 370z but it should work since it has a reverse light running light and brake light
