I bought a used stock spoiler from a member and the Spoiler has wiring coming from the 3rd brake light. its only about 5 inches long and it has a small wiring plug at the end. My question is how do I wire it to the 3rd brake light in the window? do I have to splice in some wires the extend from the window 3rd brake light all the way out to the spoiler brake light? Or is there like a stock piggyback harness that goes from the window light to the spoiler. I would obviously rather use a stock wire harness. if there is a harness what is the part number?

anyone have pics of a 03-05 spoiler install?
Please help.

P.S I have taken it to body shops and no one knows anything. If I try to get a quote to have them install they claim they wont since they dont have a template. The shops that say they can do it want to charge me $150-$200 since they would have to make a template.

I Personally would rater just swap trunk lids.

 

remove the backing from the trunk.. there will be harness there (near the trunk lock thing).. just splice off of that..u'll have to remove some foam though..

 

Just open the trunk and remove the lid liner by popping off the clips. You will see the wiring harness for the spoiler brake light. It's labeled B421 in the attached pic.

 

Thanks a lot nm3th you're the man!!! That is exactly what I needed to know!!!
That diagram is great!

 

Anyone have a diagram for the window 3rd brake light? I would like to disconnect that at the very least but cant seem to get at the light itself.

Im going to search for other posts from people that may have had to access that area. Maybe Ill be able to determine how to get the light out.

 

for the 3rd window brake light.. just remove the cover and unplug it..
to remove it.. push it against the window and lift straight up

 

Awesome! I will go try that now.
I also found this post that my help anyone looking for info on how to remove the rear deck to get at 6x9 area.

Im thinkn that I will either get the windows tinted or posiably just remove the window 3rd brake light and make a new rear deck so that there is no hole.

 

I tried this and there are only a couple of mm between the 3rd brake light and the window. I can barley move it toward the window at all be for it hits the window. So I cant lift up on it at all. I dont know how to remove the cover. I dont want to break anything.

do clips just hold the fuzzy cover in place?

Thanks

Does anyone know where to find a cover for the hole when the third brake light is removed from the car (2004 G35 Coupe)?

I called Infiniti parts ... they didn't list that part.

thanks!!
