993 how to get Horn working with RS S/Wheel?
Discussion
Had the same problem.
You need to run a wire from the boss to pick up a live terminal from in front of the steering wheel. If you do a search on Rennlist you will find instructions on how to do it. You also need to fit an L shaped pick up from the 964.

Bob,
Just in case you having problems here is the solution.
You need the horn connection part 964.652.104.00. It gets inserted into the hub as others have described. It appears that the pin that goes through the hub goes into the wiring harness and would get power there, however, it really doesn't -- there is no power there. When you insert it for the first time, look behind the hub to see where the pin comes through. You must break off the plastic that covers the pin on the back side (front of car) of the hub when it is inserted. It is best to unplug the harness from the hub to do this -- just pull it will come off. Don't worry about wires where you have to break -- there aren't any. Connect a wire from the Brown/White wire in the orange connector to the pin and use a 14/16 female connector to secure it to the pin. Now you will have power to the 964 part. Then put the Momo hub extension on. Then put the Momo hub ring (unpainted steel part with a male connector) on. Don't connect the wire from the extension on the hub ring to the hub ring. Put the washer and nut back on the steering wheel shaft and torque to 32.5 lbs. Install the steering wheel using the provided allen screws and locktite. Now take the horn button and turn it over in your hand. Install the steel ring that comes with it around the back of the horn button. There is a brass part which comes out from the inside of the back side of the button. I installed the steel ring so that it didn't touch the brass. Plug the wire from the Momo hub extension onto the brass horn connector on the back of the horn and install the horn into the wheel. It should honk.

Thanks 993c4,
sorry that I didn't respond earlier, been in Spain since the 12th.
I left the wheel off the car whilst away, and will be getting back to it in the next couple of days so that I can travel to Silverstone in the car on Thursday evening. Your info is helpful as it corresponds to my own observations as far as the adaptor and wiring are concerned. However my wheel is pre attached to the hub, so I don't know at this stage how that will affect the fitting procedure.
I will let you know how I get on.
Thanks again
Bob
