Default Going crazy looking at steering wheel options... Trying to figure out fit and wiring

So after 5zero4 did a RAV4 wheel swap (info here) I've been going crazy looking at all the possible wheel swap options. I started at the clockspring, and it would appear that the same clock spring is used for the xB2 as these vehicles (not complete, missing some models and years, especially after 2010):

Clock Spring #84306-0E010
  • Lexus ES350 2007-2010
  • Lexus GS350 2007-2010
  • Lexus IS250 2006-2010
  • Lexus IS350 2006-2010
  • Lexus RX350 2007-2010
  • Lexus RX330 2004-2006
  • Toyota Highlander 2008-2010
  • Toyota RAV4 2007-2008
  • Toyota Camry 2006-2009
  • Toyota Prius 2006-2009
  • Scion xD 2008-2010
  • Scion xB 2008-2010

Now what really caught my eye was that the IS250/350 wheels use the same clock spring and pinout, and have those sweet ass paddle shifters. The downside is that these wheels will need their own airbag (looks like around $400 used) and I can't find any info on anyone trying the swap, so there's no way to know if the corresponding plug even has the same pins hooked up to anything (so I have somewhere to tap into to wire up the shifting). The upside is that the xB2 airbag sells for almost as much, so after selling my old steering wheel and airbag I can probably do the swap for around $100-150

I did find the IS250/350 center connector pinout:

1 - Ground for paddle
2 - Display button
3 - Ground for audio controls
4 - Output for RH audio controls
5 - Output for LH audio controls
6 - Horn
7 - Paddle upshift
8 - Paddle downshift
9 - Unused
10 - Illumination

Unanswered questions:
  1. Anyone know the pinout for the steering wheel on the xB? Should be the same (minus missing stuff) but I'd like to confirm
  2. Anyone know what the harness on the back side of the clock spring (going into the dash) looks like on our car, or have a pinout/diagram or picture?
  3. What happens if I just gamble $80-100 on the wheel and plug it in without an airbag to test? Will I permanently damage something or trip some sensor running it without an airbag for a few minutes?

The best possible outcome is that our cars are already wired for this by using some common harness. More realistically I'll bet that it will fit, but the actual wires #1, 7, and 8 are simply missing and I'll have to add those to the harness. Of course there's a chance nothing will work at all.

Ok, I'll quit rambling now. I'll update the post as I do more research.

Update:

It looks like it may be possible to wire in the IS250/350 shifters along to the existing wheel and clock spring, provided there's a place to tap bolt holes and mount them on the existing steering wheel. Might need some fancy harness work. I saw a thread about someone doing it on a different Lexus wheel on a Lexus forum and got inspired. I'll keep the post updated as I find out more.

Update: it looks like this is totally possible. I need one of the following sets of items:

1. IS250/350 steering wheel and airbag. Downsides: expensive and would have a lexus wheel (non-matching airbag logo might be a red flag if I ever sell it)

2. IS250/350 steering wheel internal wiring harness (example, don't know the part number) and paddle shifters. Would possibly require cutting of the harness to fit the existing xB wheel buttons, and would require cutting the back cover of the steering wheel to mount the paddle shifters. I think I'm likely to go this way, but I have to buy a complete IS250 wheel to even try. I'm planning on taking one for the team and going for it as soon as a reasonably cheap one comes up.

I'm still working on the dashboard side pinout of the clock spring (can't find info on it anywhere), but at worst, I believe I may have to add 2-3 wires to the connector and run them to the shifter.

Outstanding questions for option #2:

1. Does the factory xB steering wheel audio control (84247-12070) use the same connection as the IS250/350 buttons do
2. Are there any other unknown differences in the clock spring or airbag wiring? (don't think so, but will have to inspect in person).

Yes, I know I'm talking to myself, just trying to keep this all documented

So here's where I am at - haven't had time to actually order anything, but will sometime in the next couple weeks:

* IS250/IS350 steering wheel should physicaly fit and wire up to the clock spring
* IS250/350 airbag cover looks like it will work with the xB airbag - should be able to transfer it over to a new empty cover.
* Paddle shifters will require adding a couple of pins to the column side connector, but stock clock spring should be fine.
* May have to move some of the existing wires on the column side connector, but it looks like the pinout really is the same for the horn, audio buttons, etc.

How did you go on gettin the is250 wheel in your box? If it helps, I'm pretty sure the xb airbag will bolt straight up to the lexus airbag cover. They are available on aliexpress for $45 without the lexus emblem. You would need to either get a lexus emblem or grind down the center to swap in your scion emblem.

The lure of those extra buttons was too much for me to resist, so I made an offer on a IS250 steering wheel on eBay and they accepted, so it looks like I'll be able to answer some of these questions in a week or so. If all goes well, I will be selling my rav4 leather steering wheel for $50 local pickup, or plus shipping if anyone is interested.
