Steering Wheel Fitment Question: 997 on a 986?

[husker boxster]

I have my std Cayman steering wheel on ebay and got a question from someone today asking if it would work on a 2004 Boxster. The ebay fitment guide doesn't list it but they list it working on a GenII 987, so I'm not sure I trust the fitment guide as gospel. I got home too late to contact the dealer, so thought I'd throw it out to you guys. My inclination is it won't work since we're talking 987 vs 986, but I don't know that for a fact. Would assume the airbag wire looms are different. Anyone have any knowledge they can drop on me?

BTW...
The part # is 997 347 804 03 if it makes any difference.
