I did use the heat shrink and took pics that I can post once I get them off the camera. I will try to post it on my website too asap, but really busy right now with work and other obligations.

For the wiring, it's very easy since the universal sensor has the same wiring colors as the old sensor. I just wired black to black, gray to gray and the two whites to the two whites. The two white wires are interchangable so it doesn't matter which way you wire those two. I also used some of the plastic wire shielding to protect the connectors from the heat. It's the tubing that looks corrogated with a slit down the side that is used to bundle wires together.

Btw, you can't search for the Porsche Boxster O2 sensor and find it. The part number is USOS-4000 and you will usually find it listed under Lexus and Audi vehicles. I found them Speedy Auto Parts for $34.64 each so it's even better.
