Steering wheel swap guide, this is not common "how-to" but just small guide... Options

[malpaso]

At last I had some time for another upgrade. Steering wheel swap... My stock one was 4-spoke with airbag/horn in the middle.


Just history now . Since today I have this one genuine 7th gen. Celica/91-04 MR2 st. wheel.


Although horn mechanism and airbag connector were different everything is working now. And I'll try describe here how generally do that... believe it will be handy for anyone

step no one: remove old steering wheel
Two screws on sides (behind small covers) holds airbag part




There are just two plugs inside. That yellow one is for airbag and white is horn (there is possibility also for cruise multi switch, where are many more wires. Horn wire is black, every time that last on right connected to wheel body)


When you unplug everything + unscrew nut in the middle you should remove wheel with puller (w/o that it's not possible at all)


step two: solving airbag connection


Different airbag connector means find right module (spiral) for it...


...or use same airbag refill




Of course... some customization should be done if airbag refill has different size (more are different, more custom work is needed). My one was just bit different... and airbag part was easy take into parts.


step three: solving horn connection
This step depends on type of horn you have. However every time it's about find how horn mechanism works, cut black wire off old wheel and connect it somewhere... It really depends on that horn mechanism. However it's really easy, just one wire to screw... somewhere .

step four: piece everything together
Installation of new wheel body (with same center bore of course) is easy...


...and in my case screw horn cable to airbag body (not wheel body like stock one)...and all finished .

Since this thread is pretty much the most thorough how-to-swap-your-steering wheel, I'd love to see it completed with information on how to splice in the 7th gen cruise stalk for those of us not lucky enough to get a 98-99 or whatever it was that's plug-n-play.

As a side note, in the interest of consolidating info, here is how to clear the airbag code, as per the BGB for a '95 USDM Celica

CLEARING CODES
1) At DLC, connect a jumper wire to terminal Tc. See Figs. 11
and 12. Connect another jumper wire to terminal AB. Turn ignition
switch to ACC or ON position. Wait about 6 seconds.
2) Starting with terminal Tc, apply body ground alternately
to terminal Tc and terminal AB twice each, in cycles of 1/2 to 1 1/2
seconds (sequence is: Tc, AB, Tc, AB). Finally, keep applying body
ground to terminal Tc until air bag warning light flashes quickly,
indicating codes are cleared.
NOTE: When alternately connecting jumper probes to terminals,
simultaneously release one probe from one terminal while
connecting other probe to other terminal. If time interval
between probings exceeds 0.2 second, codes will not clear.

Edit: Samir, I'll email you the PDF out of the BGB - it's got diagrams and PICTURES! lol

Edit again: Here's the PDFs for anyone else who wants them. "srs.pdf" has the wiring diagram, "airbag restraint system.pdf" contains trouble shooting, reset info and codes interpretation
