Boxster OBC Wire and Switch Kit
 

I did the OBC hack some time ago and controlled it using two painted dash switches, as I have just added the stalk set (because I added cruise as well) the switches are now spare. I put them up on ebay, the auction includes two painted switches, all the wires and a 911 batwing with switch holes (if you want it). Everything you need to do the full OBC hack (assuming you have OBC enabled). Just thought I'd post the link in case any of you are interested.
