guys, i got the stock spoiler after i got my car
and i didnt install the brake light on the spoiler yet

does anyone know how ?

in fact, i actually want to disconnect the forth brake light too
( the one next to the boss 6x9s )
and only use the spoiler one.

 

Lemme guess.
1. Tap into the existing brake light.
2. Remove the bulb from the deck light.
3. Search in the "BodyKits , Exterior , Lighting" forum!

 

If you have the stock spoiler, the harness should just plug directly in on the underside of the trunk lid. I saw a picture of that connecter on here somewhere.
