JD, thanks for the input. What I actually purcahsed was not an upgrade kit, but the OEM parts. The eBay listing is at
99 01 Porsche 996 97 04 Boxster Xenon Headlight Assembly with Harness | eBay and it includes two lights, original harness, and computer. I was wondering if I purchased the remaining parts if I could upgrade to OEM specifications. FWIW, I do have a PST2 available.
