Hey guys, I'm installing the factory spoiler on my car. my 03 did not come with one. I have a diagram for the wiring and it says the 3rd brakelight on the spoiler wires up to B421 but I am having trouble locating it inside the trunk. any ideas guys?

 

remove the black piece that's attached to the trunk.. and there's the plug..

 

Alright, thanks alot. I can just splice into the wires i'm assuming and tie the wires from the brakelight on the spoiler into them? cause the spoiler doesn't have a plug only a posi and nega

 

the spoiler should come with the plug.. i don't know if u can splice the wires. maybe other ppl can chime in...

 

you should be fine splicing the wires...all it is, is + and -....i did the opposite and just tapped those lines to run a 3rd brake light.

 

did you get an OEM spoiler from the dealership? make sure you got the underbody air diffusers too...

 

You can splice them with no problem, i ordered my spoiler and it didn't come with a plug so i spliced it and it's still doing fine a year later

 

Thanks guys, nah it didn't come with the plug but i just spliced into the wires and it works just fine. I dont think mine came with air diffusers either though, will that matter? and just curious for some of you guys who did this before did you guys wire it up to only light up when the brakes are pressed or did you guys wire it up to where it stays light and then brightens as the brakes are pressed?

 

it should just light up once its pressed and go away when released.

 

Im pretty sure it just lights up when i step on it and it doesn't stay illuminated when im off the brake

 

no it is only illuminated when you are pressing the brake no running light

 

if you bought OEM, how much did you pay?

 

wut about the third brake light inside the car. are you gonna dissable / remove that one? Can it be done... easily?

 

wire with brakes so u dont burn out led's

 

Mine was $130 shipped and painted to my car color. So it's a pretty good deal if you ask me. I just finished installing it, i'm going to post pics up later today so you guys can tell me how it came out. I mounted it alittle different though....I went further back flush with edge of the trunk then most G's I believe.
