OC 991

Thanks for taking the time to provide the info.

The wing has to be in the "up" position in order to remove it, so theoretically the wing break light would be active... even had the damn break light in the hands of the tech while I pushed the brake (before final install) and he said it worked...

Funny thing is I got 10 pages of Porsche tech procedures from the dealer technician describing the full steps of how to remove the seat and re-wire the brake light.
All this is part of the re-coding and install of an OEM duck wing...
No mention of a harness replacement at the wing end.
Though it was strange for Porsche to instruct their techs with splicing instructions for the install of an OEM wing.

Anyway, the damn thing is on and is a pain to remove, I'll look having the break light corrected when it's time to clean the air intake filters etc.
Gone are the days of the 996/997 where you just taped off the micro-switch to "fool" the ECU in activating the wing break light.
I'll definitely look into the harness though, my personal preference rather than splicing and creating my own.

Wow, ok sounds like I am not the only one having the 3rd brake light issue.
I ordered and installed the DT kit from Suncoast.No sunroof module.
No problems with the install as it was straight forward and having the install instructions from fellow Rennlister Plenum, made it it simple. Thank you Plenum.
Prior to getting the dealer to re-program my car I kept getting a 'check high level brake' yellow warning every time I press the brake. I thought that it may disappear after I had the re-program done.
After the dealer visit, the 'spoiler loss warning' disappeared great but still getting the yellow brake warning and no 3rd brake light illumination.
Had my very good local Porsche independent try and get it sorted , they too did a re-program of the car and made sure that it was checked off as a car with the aero kit but the same thing, puzzled is an understatement.
I have done the driver side under seat re-wire that my car requires as it is a build date of sometime late in 2011 but is a model year 2012 launch vehicle 991 so falls under the pre 18th week of 2012 build.
The kit came with two harnesses, one for a cabriolet and one for the coupe, tried both still no brake light and still getting the yellow warning every time i hit the brakes.
So I rigged up the original spoiler which was taken off in the up position and piggy backed my ducktail onto it and low and behold, DT brake light works and yellow warning is non existent.
No idea what to make of all this...Not very happy at all as I can't find a solution other than running a separate input to the DT from picking up a hot from the brake lights as suggested by another forum member in this thread. Not how I would like to have it working to tell you the truth.
Must be a simple coding issue somewhere...
Any input from fellow members would be greatly appreciated as I'm lost...
Thanks In advance..

I have a 2015 991.1 S Cabriolet and I would like to add the Cup Aerokit rear spoiler. I have the factory ducktail installed already and want to add the rear wing. But the question, will it work with cabriolets? Or do i need to go to aftermarket?

Thanks in advance.

Porsche only recommends the Cup rear wing for the Coupes. These are all wind-tunnel designed so they must not have liked the aerodynamics with it on a Cab
