Yea, it'll fit... but you'll have to wire the CC yourself.

First, you have buy an exact air bag to go with that wheel.

Second, (Important)
Depends on what year of your SC is. Earlier model uses single stage air bag system. If I remember correctly only 98 or 99 or newer SC uses double stage Air bag system.

This wheel on eBay musted the be the double stage air bag system.
Even though you find the air bag for it, if your SC is single stage air bag system(older model), air bag will not work.

Do a search with double & air bag, you will find the discussion about it.

What are single and double stage airbag systems?

silversprucesc3

If not mistaken its the way the airbag is discharged or deployed.
I would believe that single stage means fully deployed in what burst while double is a 2 stage
meaning airbag deploys to full expansion in 2 stages??
The issue would be the computer module and the connector if attempting to connect a 2 stage to a 1 stage... I have HEARD that it will not deploy if in an accident..
This is what I believe although no expert..

A single stage airbag deploys as fast as it can. The newer dual stage airbags deploy a bit slower so the force is not so strong.

CleanSC

Dual stage airbags have two charges in them. One, at about 3/4 the strength of the 2nd. In less severe accidents, the airbag ECU will only deploy the first stage. In more severe impacts, both charges will be triggered.

Sensors in the seat will guage your weight (butt sensors) and height (seat position) and make a decision on which charge to slap you in the face with. If the seat is all the way up the driver is smaller so they go with the lesser charge.

The whole point is to custom tailor your airbag to your body and severity of accident to decrease burns or other airbag-related injuries.

Now, could a dual stage bag be used on a single stage car by just wiring up the bigger bang charge and converting it to single stage use? I'm pretty optimistic and going to say most likely yes.

Would I risk my life on it to find out? Hell no. I just got the single stage bag.

Wouldn't that be all he would have to do?

CleanSC

Yes. But everyone was asking about the dual stage that are readily available and cheap. The single stage is available on only one model, one year (01 RX) so it's a major bish to find one used. You basically just need to pay the premium at the dealer if you really want this upgrade.

I have seen quite a few sc's with the 3-spoke steering wheels. how is this accomplished?

CleanSC

The '99 and '00 SC's are factory-equipped with the 1st-gen Lexus 3-spoke wheel. That's the more squarish one that was also in the earlier RX's and 2nd gen GS's.

Will the 1998-2000 OEM Lexus LS400 steering wheel be compatable?

CleanSC

I've said many times that just about ANY Toyota/Lexus wheel will work.
