Hi All.
Sorry this might be a bit of a late thread to this post, but like Garry I have also put "Ring" DRL's on my Boxster, this is the thread I placed on my UK orientated Boxster forum:-
"Put my DRL in tonight, was pleasantly surprised as well, when after connecting them up to a direct feed from the battery, just to see how they looked (and if they worked ) they came on but went off after a few seconds,

I thought I had a duff set,

but I carried on with the wiring and when i contacted them through in line fuse to be on the safe side, they again only stayed on for a few seconds,

but as soon as I started the car they came back on and have stayed on as long as the ignition is left on, and switches of when you turn the engine off. saves me looking for a switch, was going to get one from Cardiff Porsche £33 + vat, :lol not now:
So to answer a few questions
1. wire them up direct to your battery.
2. If you want them to dim down when you turn your side lights on , there is a wire there that you can connect up to your side lights.
This one is with side lights and fog lights on as well.
Here are a few photos of my Boxster.
Hope this helps someone.
Guvs.
