Yes. It's easy since everything in the Boxster is electronic. All you have to do is replace the current turn signal stalk with one that has the cruise on it. You might as well get the one with cruise and the OBC and you can have everything turned on at once. I'm not sure, but I believe you need to have a dealer turn the cruise on in the computer. The OBC is already turned on (that's why you have the outside temp on the dash). You have to wire the cruise connector and OBC to the new stalk and you're ready to go. If you search
Renntech you can find the instructions for wiring everything.
You can order the parts from
Sunset Porsche. If you tell them what you are doing, they can look up the small connectors you need to do everything. Make sure they know there is another connector for the OBC if you do that too. When they look it up, most others were only adding cruise control so I ended up having to order the other connector later. Also ask them to add the two self-locking screws that attach the airbag pack to the steering wheel. They need to be replaced after you remove the airbag. The 4-way stalk was ~$150 and the misc. wiring parts were ~$15 plus shipping.
Good luck!
