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
- Anyone know the pinout for the steering wheel on the xB? Should be the same (minus missing stuff) but I'd like to confirm
- 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?
- 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.
