Spoiler Harness - for vehicles with after-market/upgraded rear spoiler. Easily replaces your stock decklid harness, and allows for the third brake light to function. If you have a spoiler warning light on your dash, you will have to visit your local Porsche Service Department to disable the Spoiler Warning Light. Ideal for 2001-2005 Turbo, Turbo S, or GT2 models with upgraded spoilers.
