Hi. I fitted a 993 RS wheel to my 996 and came across the very same issue. I eventually solved it by running a cable from the original horn earth and soldering it to the collar/bracket that secures the switch gear onto the column. I can't claim credit for this fix as I got some great help off the 911 forum.
not sure if anyone cares but if you guys are bored like me during the covid times then you can watch pretty much all the new series on InstaFlixxer. I've been watching with my girlfriend for the last few months =)
I , too, ride momo prototipo. love it. however, I have been eyeing california, indy, grand prix (as I love the wood feel). The only thing I do differently to most folks is that I install a horn button elsewhere to avoid cable snap when turning.
Another option recently suggested to me is the NRG hub that retains the clock spring - it's a bit bulkier than the Momo to cover the clock spring but might be just what you need
I would say it’s an alternative option rather than a better option - they both have their merits. The NRG solution certainly makes installing simple and would make swapping between a standard and aftermarket wheel quicker 👍
The Contact pin 999.652.639.22 I picked up from my local dealership parts desk. All parts are in the video description. Google the number and you should find it 👍
Great review, I believe you’ve had some miles covered after your mod07 being fitted. Does the dish offset causing any difficulty reaching wipers/indicators controls in daily use?
thank you! It takes a little getting used too, as the reach is certainly longer - but after a while you just get used to the new position and it becomes normal again. It's no problem. The one thing i would recommend is an eccentric spacer as it lifts the wheel to better see the dials (the original Porsche wheel is eccentric spaced) - note it does add about 15mm to the reach.
great videos!...I am doing the same project on my 1998 base boxter with a 350mm Prototipo in black leather...I purchased a Momo Hub kit pn# 8107...I noticed that it doesn't look the same as the one used in your video...what part # is the hub kit that you used?...keep doing what you are doing!...Thanks much,
Now you’re asking, I’m not sure if I have the part number without dissembling it and looking at the stamp… I’ll have a look to see if I have anything on the box
No worries Seamus! No clock spring in this setup; the clock spring is the modern way of transferring the positive and negative to anything electrical on the steering wheel - e.g. horn / airbag. With this modification we are going old school with the positive contact being made by the copper slip ring and the negative being to chassis via the steering column 👍 If you want to keep the clock spring NRG have a neat hub solution that incorporates it.
Steering wheel looks nice buddy ;-) I believe I've seen a discussion on the 911uk forum about the same issues. I've been considering doing similar with mine but think after seeing this I might be getting somewhere to fit it for me if I do 😆
The live side of the circuit just needs an earth to sound - e.g. if it touches the chassis it will sound. If you connect the two wires you complete the circuit and the horn will go off. The horn button breaks the circuit and only when you press it, should it connect the circuit to sound the horn. So two ideas - you could have introduced an earth by accident; or your horn button is in a closed position. Have you checked with a multimeter?
Just saw the washer, what type of washer was it? Hi, I see this phrase, "996 and Boxster required a washer for the nut to properly tighten" , but no one explains what kind of washer or provides instructions. If you have any advice on this it would be greatly appreciated
Look at 16:30. This comes as part of the momo kit; it’s needed as the thread on the column are not deep enough for the momo hub and therefore this packs out/spaces the nut far enough to be on the threads. Its approx 10mm tall.
Your video was awesome. I did the same mod but when I turn the wheel aprox 3/4 turn the horn goes of , is only one spot when I turn that triggers the horn, do you have any suggestions. Going crazy here
It could be that 3/4 turn is the only spot your steering column has a good earth and hence the horn sounds as the circuit is complete - check my steering column earth video see if that helps 👍
Great video. have the same issue with my 993. I ran the second earth cable from the clock spring to the steering but still the same issue. Driving me mad.
Another great informative video I'm definitely thinking of doing the same thing now Was wondering if you could list out all the parts I need to do the conversion please? That would be really helpful Thank you!
Great video, gonna be doing this on my 996 when i get a free weekend. Would be great if you could do a follow up video of how you fix the horn issue once you work out what the problem is... then i can do the same😀😀
sweet. just one question. the big thick washer and sprung washer that you put on to fix the momo hub, does that come with the hub assembly or is it part of the original wheel fixing or do I need to buy that as well? if so could you please let me know where you sourced them?
steve wright the sprung washer and nut are the original and the big thick nut came with the momo 996 hub set - I got this from the seller ‘bellavolante’ on eBay 👍
The spring you should be able to get from any Porsche parts shop - you need part: 964 horn contact 964.652.104.00. The slip ring itself comes with the momo hub.
How have you found the Mod.07 itself? I need to replace the wheel on my modified 2nd gen Surf, it has a Momo installed but the spacer is too short and it used to be suede but now it's a crumbling mess because a previous owner put a suede wheel on a vehicle used for actual off-roading. I'm looking at the leather version like this one so I can use the existing spacer and get some room between the wheel and the wiper/indicator stalks.
I love it; I used it first without an eccentric spacer which meant losing the top of the dials. With the spacer it’s perfect. It also has great reach - the dish of the wheel brings it closer than stock.
@@TheThrottleCable Oh yes, you're right! I didn't think of better visibility of the dials. I can't see all of mine either the way it's configured since the dish is around 40mm. A deeper dish will help. Thanks for the reply; I think I'm sold.
Damn. Well you need it of course to revert back to an airbag wheel. I actually bought a spare so I could use the plugs to make an airbag resister. They are readily available, I bought my spare from eBay. 👍
Yea I know its a dumb question 😅, was just thinking not a lot of electronics in the wheel now lol.. i found one on Ebay and will harvest for plugs found an airbag resistor so should be ok looking for the brass horn plate
Glad you took my advise and went for a mod O7. You have just made me doubt myself with regards to the horn and been and checked mine works with the ignition on and it does. Could you not use the spare earth you taped up to earth the column surround? Not sure what I did as it's a few years back but nothing technical as I recall it worked straight away?

Thanks David, and yes I am going down a similar route. Testing with my multi-meter I have a good earthing point where you suggest.
Mine is apart for the RS wheel as well, but I can’t picture what part you’re soldering to,, part of the big “M5” plate or somewhere behind?
Thanks for the channel and this video, im new to working on my 911 and this video was watched several times ! Thanks m8
Glad you liked it - cheers!
That wheel looks perfect. Something I want to do with my new 996. I have one on my TVR and they’re so much better with sporty cars
The smaller diameter works so much better too I think 👍

Always good to have some choices in life! I must say I’m confused with ‘cable snap’ on the wheel? What on earth have you experienced?!
Amazing… just what I’ll be doing soon!!! Thank you ;)
Cheers Alex, good luck!
The wheel is a nice touch👌 I have a MOMO cup style wheel but haven’t fitted it yet. I don’t do electrics 😂
Another option recently suggested to me is the NRG hub that retains the clock spring - it's a bit bulkier than the Momo to cover the clock spring but might be just what you need
@@TheThrottleCable this seems like the best option. Because it would solve the problem of the washer/spacer and the horn wouldn’t it?

Mate this looks soooooo good!!!!

At 16:32 you talk about needing those spacer washers. Where did you get those, or what thickness are they?
The spacer is part of the momo/Porsche hub kit. Sorry, but I don’t know exactly what those dimensions are as all parts are now installed.
Thanks a lot man. Helped me tremendously.
So, you don't reinstall the clock spring?
No worries Seamus!
No clock spring in this setup; the clock spring is the modern way of transferring the positive and negative to anything electrical on the steering wheel - e.g. horn / airbag.

Thanks man the copper spring horn connector just needs to sit on the right place so that the connection is flawless
Well done 👍 once the adjustment is correct you’re good to go!
@@TheThrottleCable Thank you! 🙂
Good work. I have a question. Does it come with Airbeg? If not, it is illegal in New York where I live.
No, you are removing the airbag by swapping to a momo
Just saw the washer, what type of washer was it?

A little bit of copper grease helped with that 👍

Hey mate David here you a red Porsche too
good spot ;)
Where did you get the contact brush block that slips through the hub to power the brass ring for the horn?
It came with the momo hub set but you can pick it up from Porsche direct - part number in description 👍
Thank you for the informative video. Is the clockspring still in there?
Hi; the clock spring is not needed in this setup. The power feed for the horn is replaced by the copper slip ring.
@@TheThrottleCable thank you. Keep up with the great videos. Appreciated!
Where donyou get that copper plate 😅 for horn m8 ?
It’s a Porsche part; you can get it from any Porsche parts specialist or OPC
Another great informative video
I'm definitely thinking of doing the same thing now
Was wondering if you could list out all the parts I need to do the conversion please? That would be really helpful
Thank you!
Hey Alun, thank you. You should find the details you need in the video description. All the best!
@@TheThrottleCable Oh yeah 🤣
Thank You!
Great video. What did you torque the shaft nut to?
Torque spec is 33 ft lb
Great video, gonna be doing this on my 996 when i get a free weekend. Would be great if you could do a follow up video of how you fix the horn issue once you work out what the problem is... then i can do the same😀😀
Yes; it’s possible to earth the steering column directly from the just behind the squib - got the tip from Marky911👍

@@TheThrottleCable many thanks, i didn't buy the kit, just bought the boss on its own. Any idea how thick the spacer needs to be?
It’s appropriately 10mm Steve, I’ve not measured it but that’s my guess
Hi, was wondering how you where you got the copper clock spring to ground the hub
The spring you should be able to get from any Porsche parts shop - you need part: 964 horn contact 964.652.104.00.

Hello .is there a Air bag in the wheel from momo
No, you are removing the airbag by swapping to a momo
@@TheThrottleCable ok then we need big balls to drive without airbag
Where did you get the brush for the horn
Any Porsche parts supplier - part numbers are in description
I want to do this on my 2001 Boxster but would it pass an MOT without the airbag?thanks
most likely will depend on your local tester - i would go talk to them if you have any concerns
As long as the airbag warning light is off its fine
Do i need the clock spring i think i broke mine when ripping the wheel off 🔧😅
Damn. Well you need it of course to revert back to an airbag wheel. I actually bought a spare so I could use the plugs to make an airbag resister. They are readily available, I bought my spare from eBay. 👍

Hey man! How deep is the dish on that wheel? :)
The dish is 70mm
The wheel diameter is 350mm
Rim thickness 28mm
Awesome!! Thanks alot! Looks awesome
Glad you took my advise and went for a mod O7. You have just made me doubt myself with regards to the horn and been and checked mine works with the ignition on and it does.

Yes for the negative line I was thinking just the same, however I’m not sure where would give the constant negative needed 🤔
@@TheThrottleCable maybe the plate that the contact pushes through? Be easy enough to test with a meter?
