INSTALLED STEERING WHEEL AUDIO CONTROLS ON MY 08

INSTALLED STEERING WHEEL AUDIO CONTROLS, BT CALLING CONTROL AND VOICE ACTIVATED CONTROL

I didn't like the fact that my SR5 Taco steering wheel didn't come with at least the basic controls; volume, channel and mode. Got pretty much your plain jane steering wheel. And since I upgraded to a 2014 touchscreen with NAV, this was something that would go great along with it. I've searched TW if it could be done, but came up with no write up or any info at all.

Toyota tends to pre-wire their vehicles even though you don't have that certain feature. First thing I looked for was the wires that led to the headunit. This 3 wires.


At this point I took the plunge and ordered the parts, even though I wasn't 100% sure all wiring was there beside those 3 wires.

PARTS NEEDED
10mm socket
19mm socket
T30 Torx bit
Tape
Marker
Toyota Tacoma Spiral Cable: Part #84306-0E010($244.31 total with shipping)

TRD Sport airbag.($335.91 total with shipping)


Switch Steering Pad, left side.($80.66 w/out shipping)

Switch, right side.($69.76 w/out shipping)

Cable ribbon that connects the right switch to the left switch.(30.43 w/out shipping)

Got this 3 parts from one website. ($194.35 total with shipping)

As you can see it ain't cheap to upgrade. But I hated when I had to reach over and touch the touchscreen just to change cannels, volume etc. Upgraded to a 2014 Entune HU w/NAV and App Suite, so it was fitting to upgrade to this.

STEP 1
Park your truck and keep the steering wheel straight, make sure your wheels are pointing straight.

STEP 2
Disconnect the battery terminals by loosening the 10mm bolt. Just to be on the safe side, I removed both the neg. and pos.and wrap them in plastic. Kill some time to at least discharge the system completely before proceeding to Step 3.


STEP 3
Apply tape to the top of the steering wheel and the column and draw arrows pointing towards each other. This is to make sure you have the right alignment.


STEP 4
Remove the cover on both sides to access the T30 torx screw.



STEP 5
You will see two T-30 torx screws in here. Using the T-30 bit, unscrew these as much as you can. Please note that they will not come all the way out, that's ok. This loosens up the airbag for removal.



STEP 6
Remove all wires leading to the airbag. To remove the Orange and Black air bag wires, you must first pry up the yellow tab to release the grip and then you will be able to actually remove the airbag wires.


Remove the brown ground wire from the bottom of the airbag.




Place the airbag, Toyota logo up somewhere safe.

STEP 7
Disconnect the brown plug from the spiral cable


STEP 8
Remove the 19mm bolt with the 19mm socket.


Steering wheel should be easily remove by gently pulling up.


STEP 9
Remove the 2 phillips head screw driver and remove the top and bottom plastic trim pieces. I had to mess with them a bit, but they will come out. Just be sure not to muscle too much so you don't break any of the tabs that hold them together.


STEP 10
Remove the 2 connectors on the bottom of the clockspring. One is black(steering wheel contorls) and one is yellow(airbag).


STEP 11
Remove clockspring by disconnecting 3 plastic tabs. One on the top, and 1 on either side.
Top.

Left.

Right.


Remove clock spring and put it someplace safe.

STEP 12
Install new clockspring. It's already centered via the orange tab that keeps it from spinning. You'll snap this off later. Reinstall your plastic trim once CS is inplace. After this step, pretty much everything is in reverse.



STEP 13
Pull your orange tab off freeing up the clockspring to spin, but keep it centered. Reinstall your steering wheel with wires feeding through the top. Line up the steering wheel, making sure its straight. Tighten the 19 mm bolt. Install the brown plug.


STEP 14
Connect the ribbon cable to the left and right side switch.



STEP 15
Install the switch pad on the steering wheel. Plug the green plug into the the spiral cable.


STEP 16
Install brown ground wire, orange and black spiral cable plug on the airbag. Make sure airbag is flush with the steering wheel controls and re-tighten the T-30 torx screw. Replace the cover on both sides. Reconnect both battery terminals. Turn ignition to Acc. position and test everything to make sure it works.


Volume + & - works, Channel < & > works, Mode function works, Bluetooth calling works and Voice Command Activation function works. Everything's working flawlessly and yes this is on an 08 without any of that fancy premium package.

Only work to do now is run the mic somewhere clean and stock looking.

If you guys want more proof that it works, I can put up some vids.

WARNING: The airbag light may or may not come on(on the dashboard) after the install. After my install the airbag light stayed on. What I did was disconnect the battery terminals, waited for a few minute, re-connect it and the light went away. So I'm just putting this out. Do this install at your own risk(see disclaimer).

 

That's awesome! I hate the dead switches on the right side. Great build!

 

Dude awesome DIY! Thanks! I might have to look into doing this, Id just love to have the damn Volume buttons!

 

Very sweet write up !! Could you add the part numbers and prices .
I have the left side controls but no bluetooth on the right side .
Wondering if this is an affordable upgrade ?

Here is another post on Tacoma World showing the bluetooth install with wiring schematics

If you already have the left side controls, I think all you would really need is the right side switch and the ribbon cable.

As for the price, not gonna lie, it'll cost you some. But if you guys want me to put up the price I'll do that. Let me gather them up first then I'll update this.

*UPDATE*

Just updated with the prices.

 

Awesome. I love stuff like this.

Im in the middle of sorting out a '14 non JBL w/ nav radio swap into a 2011.

I have a few questions about this swap.

I have the volume/mode controls, but no bluetooth/voice command stuff.

Are there 3 different clock springs or just 2 different ones - no steering wheel controls vs steering wheel controls? Or are there 3 different clock springs - one for no controls, one for volume/mode controls but no bluetooth/voice command stuff, and one for all the controls?

I would like to add the BT/voice command stuff to my truck. Hopefully its as easy as adding the BT/voice command buttons and ribbon cable to connect them.

As far as plugging the controls into the new radio, its a simple as plug and play or is there anything special needed?

:beer:

 

From what I've read before doing this install, there's only 2. One for the plain jane steering wheel, and the 2nd one for the steering wheel with the integrated audio control.

Since you already have the steering wheel audio control, looks like all you need is the BT calling/voice command switch pad and the ribbon cable. Which I listed the part number on post 1.

The BT calling/voice command switch pad runs off the same line as the volume-channel-mode switch pad. That's why there's the ribbon cable that connects the right side switch to the left side switch(hope that makes sense). That's why all you really need is the ribbon cable and right side switch pad.

 

Awesome. I did some reading after posting and thats what I came up with on another site.

Thanks for all the help. :beer:

 

Oh god.. now you're making me install the bluetooth controls on the right side of my steering wheel! Must have.. been wanting this since i put in the new head unit

 

Mean write up bro. Just wondering why was it necessary to put in a new clock spring? Is it just on your 08 or do you think i'd have to do same kine thing on my 13?

 

Because the clockspring has all the wiring in it and the correct plugs needed to add the buttons so it's all plug and play
Hence why they call it a "spiral cable assembly"

 

Oh ok! Thanks. Def gonna try n do this mod now

 

If Toyota didn't completely re-design that part with the newer model year, then I'm pretty sure all you really need to do is swap parts. But just a warning it does get pricey.

 

Have you hooked up the microphone for the bluetooth? I was told its in the rearview mirror along with the autodim/compass

 

Negative. The mic plugs directly into the 28-pin conversion harness and that harness plugs into the headunit.

 

Nice write up!

 

Thanks. Well worth it

 

Thanks for being so detailed. I just need the new clock spring and it's not the one covered under the TSB...16 pin vs 7 pin. Anything too technical about the CS install portion? Looks pretty straight forward?

Thanks,
~Brett

 

Nothing to technical. Just be careful handling the airbag. And a warning, the airbag light might stay on after the install(on the dashboard).

 

Does the airbag light go away?
