Hey guys, i have the RS wheel from Gert. I went to install last night and now i'm completely confused. After removing the wheel, i see a plastic ring with the wiring for the steering wheel & airbag coming out of it. now the wheel does not fit over this, so....... do i remove the plastic ring somehow?
i'm quite confused as to how this wheel fits properly.
oh, hes i do have the brass piece to make the horn functional (thank you Gert), of course i have no idea where it goes! any help would be greatly appreciated.
i'm no wiring guru, so i welcome the advice.
Cheers,
Kyle.

Here's Joey Bagadonuts' DIY description, with this it should be easy:

Momo wheel installation made easy!

Here you go Doug and Erick. I'm working from memory and notes but I believe these instructions will get you most of the way home. Let's start with a few disclaimers:

- Disabling the airbag is not recommended by the manufacturer
- The Momo adapter hub #7004 is not a perfect fit with the stock column collar. You must modify the hub collars to complete this installation (see below).
- Disconnecting the airbag may activate the warning lights and require a trip to your nearest Porsche dealership to reset (usually a five minute job with the Bosch Hammer).

If still interested, keep reading.

Parts & tools required:

- Momo wheel
- Momo hub adapter 7004
- Porsche airbag tester 000.721.951.60 (not 9516/1)
- Porsche horn contact 964.652.104.00
- Male and female wiring contacts. The spade type often used to connect audio speakers.
- Torque wrench
- Torx T30 screwdriver socket
- ½” rachet driver with 5” socket extension
- 24mm socket (15/16" might be a better fit if you can find one)
- Phillips head screwdriver

Step 1. To begin, disconnect the battery ground and wait at least 20 minutes before attempting this installation to prevent accidental airbag ignition.

Step 2. Loosen the two screws located at 9 and 3 o'clock on the back side of the steering wheel using the T30 socket. These screw hold the bag on to the wheel and once loosened, will allow you to "lift" the airbag right off the wheel. It will be connected by a wire from the column which you can easily unplug.

Step 3. To get the wheel off the column, I used a 24mm socket BUT it was a little loose--it works, but it's not a precise fit. Loosen the bolt, remove the accompanying washer, unplug the horn contact wire and remove the wheel from the steering post.

Note: You will want to mark the top dead center location (TDC) of the steering post to facilitate installation of the new wheel.

Step 4. The column collar requires the removal of 6 phillips head screws, four on the face and two on the sides. It's tricky getting the bottom half off the column, especially if you have a cruise control stalk, so be gentle as you ease it off.

Step 5. The final piece to remove is the horn contact plate. It's a circular piece made of plastic and a flat copper ring. Basically, it allows you to turn the wheel without tangling or unplugging the wires in the hub. It's two more screws.

Step 6. Now, gently pull the wiring attached to the contact plate out from the dash. The horn and airbag wiring is sheathed in a rubber tube. Sliding it up will reveal the two plugs connected to the contact plate which you can disconnect to keep the plate intact. You will need to clip the airbag wire on the front of the plate to attach the 9516 tester.

Step 7. Now you need to install the Factory horn contact 964.652.104.00 to the stalk assembly. Do you see the curved metallic part surrounding the center? That piece passes current and makes contact with the metallic bottom of the Momo hub; without this contact, the horn will not work.

Note: The 7004 hub is the correct part but the diameter is actually just a little big. The solution is to sand off some material from the collar halves to enlarge the opening---CAREFULLY-- so that they fit around the adapter. I used the sandpaper sheet wrapped around a coke can trick to trim it back.

Step 8. Install the hub and secure with washer and nut; torque to 32.5 ft lbs. Make sure to seat the hub with one of the wheel mounting holes lined up with the post’s TDC mark. Again, the forward edge of the column covers should straddle the outside of the adapter.

Step 9. Airbag wiring. You’ll need to splice the airbag lead to the wire coming out of the dash. The airbag tester is a 2" x 1/2" wafer housed in a plastic box. Lose the box and find a secure place to locate the tester behind the steering column.

Step 10. Horn wiring. (Sorry, I'm a little fuzzy, here) You will need to mount a spade type contact to the back of the horn if two are not present. There’s a small screw hole already there and you’ll probably want to take the horn to your hardware store to find the right size screw. The screw makes contact with the coil spring under the horn button when depressed. Momo supplies a wire which attaches to the male contact located in the hub (ground) and the horn button. Route the lead (from behind the dash?) and ground wires through the hub and unattached wheel center, connect them to the horn button and press it into place along with the mounting ring.

Step 11. Mount the wheel to the hub with the six screws supplied (I think it’s 5 ft lbs), reconnect the battery and fire it up. Check the horn and drive around the block to ensure the steering hub was properly centered.

And here's image how the horn contact should be:

Good luck getting the orange connectors wiring the clockspring mechanism to separate. I cursed for several evenings while I tried to figure out the best way to get at them. Not enough slack from the top and not enough room for my hands from the bottom. I finally had to dismantle the heater box and use a pair of needle nose pliers to get at them.

In all seriousness, good luck!

wow....seriously beginning to wonder if this is worth the trouble.
not like changing the steering wheel on my SC, that takes about 3 minutes.
hmmmm....... thanks very much for the information guys. really apprecaite it!

Remember to put in the appropriate resistor for the airbag light. I tried the one Gert recommended (1/2 watt 1.8 ohm) but it didn't work for me. I am sure it had to be my method of installation as I know Gert is on the ball with these things. Got the one from www.airbagonoff.com - $30. Works great (already comes ready to install - just stick it in.

This write-up would be great in the DIY section!!! I want to do this mod sometime next year, so I'll need the info then. What's the process to get it put in the DIY section?
