Hi my neighbor just bought a 04 g35x sedan white and its the nice white . He is wanting to add a OEM spoiler and is I am wondering if the harness is there in the trunk to hook up the third brake light and if its plug and play. thanks for any info

 

yes it is. I got my 05x installed with OEM like style and the plugs are all there.

 

^ do you think the 03/04 are wired also?

 

What do you guys mean "is the harness there?" I bought an aftermarket OEM style one off eBay for like $80 and I just tapped the power into the third brake light wiring.

 

I have an 03, it has a harness in the trunk lid. You don't have to tap any wires, just plug it in.
