The Phase II Decoder, designed with the Porsche Cayman, 911 and Boxster in mind, but just at home with the likes of Aston Martin, Audi, Bentley, BMW, and a majority of other makes.
We have tried this decoder on several Porsches, the Boxters were 99% successfull, the 911 (997) we had a mixed set of results as did we with the Cayman.
By mixed set of results we mean, the hid kit / xenon kit worked and drew enough power to keep working on the Porsche 911 and cayman, however in some rare instances the on board error came on (just the once, and the tell tale sign was on, but there was no annoying continuous error messages appearing frequently).
Here is the installation guide.
There are two distinct parts to the decoder, one is a relay and one is the main body (both these parts are supplied as pairs, to cover each of the two lights).

 D – Connects to the male end from the harness (C)

E – Connects to the female end of the ballast (receiving end)

Once you have done this, repeat steps A-E for the other side (the other lamp).

In short this harness acts as a mid point between the cars original wiring loom and the hid conversion kit.

What this harness will 100% achieve for the Cayman and the 911 997, is a constant power feed in a controlled manner.
