Mr. Bibbetson did a nice write up on the passenger air bag delete.This is worthy of a DIY archive. Here is his worki:

One of the reasons (besides the great looks) that I bought a 968 was to HAVE airbags. I think my dad would still be alive if his car had had them when some drunks nailed him. I believe in them...although it's anyone's guess if the ones in my 11 year old car still work. One good thing about deleting the air bag is that you can install a cool aftermarket steering wheel though. I did that on my 928 and love it.

i have harnesses in my car, so airbags are superflous - i agree that they are a good safety item in a stock car though

Has anyone figured out a way to install a switch to turn the airbag off/on? I'd like that to allow me to put a child in the front seat.

If you use a swith, maybe from a modern car ? it is possible. But with this kind of systems you can not allowed to do some experimenting.

A switch is not a possible option. The alternative is to install a resitant. In some other topic the exact resistant has been mentioned. (I think it was about 3 ohm or a pair of them. )



By disconnecting the wires, you will have the light triggerd. And nothing is so frustrating than a big red light in front of you!.

I started a thread awhile back on whether or not it was possible to install a passenger-side airbag deactivation switch, and somebody responded that he purchased one from these guys, and he successfully installed it following the instructions that came with the switch:

I talked to these guys on the phone, and they seem to know what they're doing. It's a bit pricey at $168 including shipping, but even my youngest daughter is getting too big to comfortably ride in the back, so she's "forcing" me to take the minivan <img src="/forum/images/smilies/968/blink.gif" class="smilie" alt="" /> whenever I drive her anywhere. This madness has got to stop, regardless of price! Anyway, I'll let everyone know how the installation went, but it will be a few weeks.

I've red the article, interesting switch.

I'm interested in your experience with it. Maybe I will "switch" too!

Having the same difficulties with growing childs......

I ran into the same consideration with my 11 year old.

Solution: remove the airbag connector and stuff in a 3 ohm resistor into the harness plug. Now my son gets to ride shotgun.

Anyone else, for short trips, takes their chances. Long trips=remove resistor and plug in the bag. ( disconnect battery and wait, or rude, annoying red light goes on in the instrument cluster.

I cant see why you could not wire in a dual pole single throw switch and make the transition when the car was off/battery disconnected. Keep it hidden in the glove box with a cover over the switch, like a NOZ switch.

It's my understanding the even the slight extra resistance of the switch will trigger the airbag fault light.

[unknown4u]

Yes Anchorman it is correct what you said. But the switch has golden contacts so that problem must have gone.

Since the fault condition is caused when the circuit sees an open circuit, a slight increase above 3 ohms should not cause an error. 3 ohms was selected as a "close" approximation of the load that the airbag has in the circuit to fool the computer. It is a standard value for resistors and I would guess that it is not the exact airbag load anyway.

As far as I know, gold contact are used to reduce oxidation which can lead to poor contact between the metal surfaces, not to reduce resistance. Even if I am wrong, you can buy a switch with gold plated contacts for much less than $US165, plus it would not have to be so large and require keys to open and close.

Brian,



Your solution actually sounds pretty attractive, as I almost never have anyone ride in my car, other than my kids. Could you let me know exactly where the airbag connector is located, as well as the harness plug? And do you have to disconnect the battery and wait when first removing the airbag connector prior to installing the resistor? If so, how long? Thanks!

YOU MUST DISCONNECT THE MINUS BATTERY CABLE IN THE ENGINE BAY.

If you remove the glove box door and take out the glove box liner ( make a picture of which wires go to which location on the glove box light) you will see the airbag. It sits right above the glove box with the connector easily reachable from the glove box area. Let the car rest for 45 mins after you remove the neg battery cable. The harness plugs into the airbag, easy to remove. Add the 3 ohm resistor ( 1/8th or 1/4 watt is fine. They are hard to find. ) to the harness side of the system. Fold the leads back on themselves so they are thicker. Push them into the holes in the connector that used to mate with the airbag. Cover with black electrical tape. Cinch down the whole mess with 1 or 2 small wire/zip ties to make sure that everything stays in place. Reconnect the negative battery cable in the engine compartment. Reinstall the glove box liner and door/hinges. The car should start, test the airbag circuit and all should be well. If the resistor is not attached to the connector on both sides of the socket, the red lamp on the top center of the dash will come on and stay on. If it does you need to have it reset by a mechanic with a BOSCH hammer. You can not reset it.

Go slow and be careful that you have a good connection and it will be a piece of cake.

Great description - thanks. I think this solution will work very well for me.

I've been calling around trying to find a 3 ohm resistor (you're right, they're not easy to find, especially on a Saturday). I found a Radio Shack that has either a 2.7 or a 3.3 ohm. Are these close enough? I seem to remember from the threads covering the replacement of the stock steering wheel with an aftermarket that 2.7 ohms is the correct value. Does anybody who's done that conversion recently remember if this is correct? I think most of this discussion was on 968.net, and I don't know if the search on that site still works (I don't remember my password, anyway). Thanks.

I would advise finding a 3.0 resistor. The 2.7, 5% tolerance may go down as low as 2.565 and the 3.3, 5% tolerance may go up as high as 3.465.



We know that 3.0 works without setting off the warning system. Order on-line:

I still find the service interval requirement to "inspect" or "check" airbag to be hilarious. How - hit the front end with a hammer?



Is anyone aware of any studies or other info on older airbag operation? At the 15 year mark (later this year for my car), you really have to wonder about the functionality and stability of the entire system. Just how long was it designed to last? Is there any reliable way to "inspect" the system?

I ask an airbagspecialist in the past about it.

He told me that the "chemicals"are packed that they have a better quality than a bullit.

A bullit is still good for a deadly shot after 40 years. The only thing that the OPC does is checking the electronics with the Hammer.



Thats what they told me.

Thanks; I'm off all next week, so hopefully I'll find someone in town who has a 3.0 ohm. If not, I'll order from the link you provided.

I seem to remember seeing a video, I think in a ticket dismissal class, of a very old car with an airbag getting crash-tested, to prove the point that air bags are still functional decades after they are installed. So I don't think we have anything to worry about for awhile.

Well, I decided that rather than spending hours looking for this resistor in town, I went ahead and orderd the 10-pack from the link you provided. Thanks so much for this. With shipping, it came to $2.34; since most electronics parts shops are on the opposite side of town from where I live, I would have spent more than this in gas. Hopefully my installation will go as smoothy as yours did. And one of these days I'll use one of the remaining nine in the pack when I install an aftermarket, non-airbag steering wheel.
