Steering Wheel Install (Aftermarket)
 
There are a couple of threads I found on here that discussed doing a steering wheel swap, but no clear step-by-step. So here goes:

DISCLAIMER
I take no responsibility for the fact that you are making your car less safe by removing your airbag, or in the eventuality that the airbag deploys during the removal process and blows your head clean off. Proceed at your own risk. DANGER. CAUTION. WARNING. UNSAFE. BE AFRAID. OFF-ROAD USE ONLY. DO NOT ATTEMPT.


TOOLS NEEDED
torx T30 bit
phillips screwdriver
19mm socket

STOCK STEERING WHEEL REMOVAL

1. Disconnect negative terminal battery and wait a few minutes. The service manual says to wait 90 seconds. This allows any charge to leave the system and prevents the airbag from accidentally deploying.

2. Remove the two torx screws from the sides of the steering wheel. Pull the airbag/horn out of the wheel so you can see the wires connecting it to the car.

3. Unhook the single black horn wire from the airbag/horn assembly. The two wires sort of side-clipped to the airbag scared me so I had the airbag assembly at arms length while i disconnected them :pray:. I used a screwdriver to slowly work them out. The airbag/horn assembly should now be free.

4. Use the 19mm socket to take off the center nut. Unclip the black wire harness (for the cc/horn/audio controls) from the spiral cable assembly. MAKE SURE THE WHEEL IS STRAIGHT AT THIS POINT. The wheel will now pull free if you wiggle it a bit while pulling.

5. The entire spiral cable assembly is just clipped in and connected to a couple of wire harnesses. To access them, remove the two phillips screws facing you on the steering column cover. You can then pull the cover apart and remove the bottom half.

6. I undid the smaller plug first since it was easy to get undone, then saved the bigger one until i had the spiral cable assembly off. Just grab it with both hands and rock it side-to-side while pulling. The three clips will undo and it will pull right off. Turn it over to get at the larger wire harness plug and undo it.

AFTERMARKET WHEEL INSTALLATION

1. Reassemble the column cover and tuck the two wire harnesses out of the way.

2. Assemble the hub adapter, quick release and wheel. Use only two screws to attach the QR base to the hub adapter, as we'll be taking them back apart. Slide the complete new wheel assembly onto the hub bolt, making sure you have the wheel straight.

3. Now release the wheel with the quick release and unbolt the QR base from the hub adapter to expose the hub bolt.

4. Reinstall the 19mm hub nut, then reassemble the QR base and wheel. The End.

HOOKING UP THE HORN BUTTON

On the small black harness that is left behind the hub (next to the airbag harness) there is a single white wire thats the horn wire, tap the horn button (some might be different) to that wire but leave enough wire slack so that the wheel can be turned lock to lock w/o pulling on the wire (about 8-12 inches of wire).

my wheel/hub/qr assembly came with a little grounding ring that was between the hub and quick release, there is 2 wire inside the hub 1 black and 1 yellow, i tapped the yellow wire to the white wire in the harness and grounded the black wire to the ring.

after that step i removed the horn button off of the wheel and attached the connections on the horn to the connections on the quick release.

once all the connections were made i pushed the button and voila! got the horn back. when i take my assembly off (whenever someone buys it) i'll take a couple pics.

When was the last time an air bag blew anybodies head clean off?

I remember one time when I was installing an air bag in one of those Mercedes land rover look alikes and it was my first time installing air bags. I was in a heated argument with a co worker at the time when I was working in that shop. We were arguing while I was working and he took a rubber mallet and kept hitting the frame near the sensor to ____ me off and I was thinking good thing the battery wasn't hooked up... While he was thumping on the bumper frame the vibrations made the ground wire jump and it touch the battery terminal and I plugged the air bag in at the same time he "accidentally" hit the sensor and the air bag blew instantly. Fired and knocked me out and I didtn think those things came out so fast. My head was like half a foot away from the bag.

He got fried for costing the shop $1500 for a new bag. :relief:

I thought those death baloons were so posed to be safe :tap:

Other then that good write up! This should be a sticky, lots of people are swapping wheels.

lmao thats hilarious



Man would I love a new wheel... just the idea of not having a bag scares the crap outta me :nails:

iKONA 09-05-2008 02:37 AM

I'm scared either way now :rofl:

Elijahtc 09-05-2008 04:52 AM

i've seen more people hurt by the bag than helped. the seat belt should catch u anyways.

Nice write up. I am waiting on the horn button and cruise control writeups myself.

here is a photo of what ur car could look like with a new steer wheel and quick release hub.

lol, i love the disclaimer

jdg1605 09-05-2008 01:34 PM

I am about to buy a wheel and a quick release, do I still need a hub adapter and if so, where do I get one for a MOMO wheel?

Im thinking of getting the NRG quick release. anyone have experience with there QR's?

D1G1T4L 09-05-2008 03:24 PM

Here's how mine turned out:

You're right, it would probably be more of a messy tearing. I was exaggerating, but still trying to remind to people to be careful because as you make clear in your story... these things aren't a joke.

You will need the hub adapter as well, yes. I have the NRG HA and NRG version 2.0 QR. The "for Toyota" HA is for Scions as well. The NRG QR will work fine with MOMO wheels. Check out weaksauceparts.com, they have HA/QR/wheel combo deals.

idk how thats possible.
they dont just go off from hitting the sensor.
its takes into account all of the following: accelerometers, impact sensors, wheel speed sensors, gyroscopes, brake pressure sensors, and seat occupancy sensors

and also, airbags cost around $500 not $1500.

dont believe me? look it up on Wiki.

not tyring to start isht...im just sayin.

HKSpeed 09-05-2008 04:28 PM

nice diy.
i wanted to put an aftermarket steering wheel on, but i didnt want to lose the stock wheel's audio controls. so i put the black/silver oem accessory wheels instead. winding up the cable wiring assembly was such a pain.

Luc1f3r 12-15-2008 01:36 AM

Thanks for the write up, i just put my wheel on, took all of 30 minutes. Thanks!

davedavetC 05-11-2009 05:24 PM

my advice, get the Momo hub and NRG qucik release, i have that set up with a Momo wheel and i dont have a gap (kinda)

06tcdude 05-19-2009 10:31 PM

Nice write up. And the battery cable touching, energizing the system caused it, its a misfunction, but can happen. I want a different steering wheel, I just don't wanna lose my CC. So I might look into a celica steering wheel

562teg 07-02-2009 02:38 AM

good write up, thanks!

D1G1T4L 07-02-2009 08:21 PM

Thanks man, I added your info the the 1st post so it's easy to find.

davedavetC 07-03-2009 05:22 PM

nice dude i hope it helps,

goodguy889 07-03-2009 05:58 PM

will this make ur air bag come on? if so damn, lol i just got my damn airbag light off my sparco seats, anyway to clear the light with resistors

Luc1f3r 07-03-2009 06:13 PM

if youre already overwriting/bypassing the dash light for the seats you shouldnt need to do anything else for the wheel. you airbag system either works or doesnt, i dont think there are zones (may be wrong) but i would think if you bypass for one area all areas would be bypassed?

goodguy889 07-03-2009 06:36 PM

well what i did was installed my airbags and did a little work on the bags so if they deploy i wont launch out my sunroof. but as of now all my airbags are working and have no light, i do know that if ur airbag light is on then all ur airbags are disabled and that what i dont want. so really i didnt bypass aything i just installed the airbags.

emerilnut 07-09-2009 01:36 AM

Did you ever relocate the cruise control main switch? Does it come out as an assembly that you could screw onto, say, a homemade aluminum bracket?

I do want change to an aftermarket wheel so that I can locate the wheel closer to me, but I'm not sure what to do about the cruise control.

bzboardz 07-09-2009 01:44 AM

i want your fisheye :)

davedavetC 07-09-2009 03:35 AM

even if you fix the seat airbag problem you'll still get the airbag light on with the wheel, the only way to fix it is a similar way to the seat fix but its probably gonna be a different resistance. same method tho.

breaux_tC 08-10-2009 12:31 AM

thanks for the write up

silver_jazzy 08-29-2009 02:00 AM

i just installed an NRG quick release and steering wheel with the help of the sweet write up and the airbag light is on. does anyone know how to turn it off? im currently zooming around town hornless. im gonna work on my horn when i get some free time. :icon_headphones:

08_Scion_tC 10-11-2009 01:09 PM

Very nice DIY. I really wanna switch my 08' wheel for the RS5 wheel, I like the red stiching :D

Sciontistical_One 12-09-2009 10:31 PM

watching...

davedavetC 12-10-2009 12:19 AM

pssst. this thread was on life support and we were about to pull the plug....

chrischoi 12-10-2009 06:10 AM

Cruise control DIY? Easy air bag solution please! Haha.

davedavetC 12-10-2009 11:18 AM

Cruise control and horn have been fixed but I haven't seen anything on the sirbag

johnhawkins 02-26-2010 09:37 PM

Is there a specific size hub that fits the tC? I bought a "universal" hub adapter and it did not fit.

GQQSE13 02-28-2010 08:35 PM

how do you get the airbag clips off? which direction do they go? i'm looking at mine right now and can't tell and dont think i'm able to disconnect it at the wheel

yellowxhoodie 02-28-2010 09:14 PM

take a flathead screwdriver and stick it under the black center part of the clip, once that pops up then you can take the whole clip out.

is this on the airbag piece or the piece that's still connected to the wheel?

GQQSE13 02-28-2010 10:36 PM

finally got mine done after some help from corey (thanks again!!!) will put pics up in the other thread tonite

chrischoi 03-05-2010 02:26 PM

Pics! I want to see the cruise control. I think I'll take care of the horn today. The air bag light is a 3 ohm resistor. You can do that at the bottom or the top.
