Took a few pictures while installing a new 993RS steering wheel this weekend. While I was able to find plenty of threads & general info about the wheel/hub, the wiring bits weren't documented so well & lead to a few surprises.. hopefully these help someone else.
The clockspring connectors are interchangeable between 993 / 996 / 986 Boxster. Ordering the wheel from Carnewal gets you the wheel/hub (duh), horn contact plug/pin, & the 2.8ohm resistor.
Part#'s:
Wheel + Hub assembly: 993-347-084-80-8YR
Horn switch contact: 964-652-104-00
Airbag connectors:

Pin for turn signal switch connector:

(anyone know the Porsche p/n's for these? I wasn't able to find anything)
Before we begin, some disclaimers are necessary due to the sensitive subject matter of defeating a supplemental restraint system:
1) By opening this post, you agree to hold the author (me!) completely non-liable for any consequences you incur (or do not incur) as a result of this post.
2) You fully understand the implications and bear the burden of removing an airbag from a vehicle, should you choose to & will not look to blame someone else (especially me) for an undesirable consequence of your actions.
3) You read this on the internet. If something goes wrong, think of how stupid you'll sound when you proclaim to your spouse, significant other, parol officer, parents etc.. 'but I read it on the internet'. Say it out loud now, in the presence of another human to convince yourself how silly this excuse sounds.
4) Your car wants you to die & will try to kill you whenever it gets an opportunity to do so. It is dangerous by nature. Do not assume that because you've named it & have 'love' for it that this isn't true. You're the frog to Porsche's scorpion here..
Disconnect the battery, wait for good measure, then remove steering wheel (already covered elsewhere):
Loosen this 8mm bolt to free the switch assembly:
Wiring bundle happily tied back for ~15yrs:
Taking a closer look, later cars (9*6) will have one orange, one red connector - they are interchangeable:
p/n 964.652.104.00
Presses in from the front:
& pokes through the switch..
adding another pin (#71) to the rear:
Problem is that this pin isn't populated in the mating connector since the horn circuit is carried through the clockspring in airbag equipped cars (photo upside down, look at the upper left cavity in the connector):

Opening the connector & viewing from the backside:
