99 C2 GT3 style wing wiring harness question

Recommended Posts

Hi everyone:

I know this topic has been repeated a million times, but in searching through them, I believe there have been some changes.

I have a 99 C2, with the factory pop wing, third brake light in the wing, etc...  I just purchased (and received), my GT3 style wing, which does not have the third brake light.

In searching for the wiring harness, it seems as though part numbers and pricing have swapped:

99661207004 is now for non third brake light, aerokit 1 coupe, and is around $125

99661207051 is now "stop lamp" (according to Porsche), and is around $390


From what I have read, the major difference is model year, and whether or not you have a third brake light; which I am reading as "spoiler third brake light, not the one below the rear window."

Is this the case?  Or is 51 still the correct one and inflation took over?


If I do decide to jumper wire the pins, is it 2-5 or 1-5?  Somewhere I read that on 99-00 it is 1-5.


Thanks in advance for your help.
