Steering Wheel Controls Swappable?

My understanding is that it does have the necessary connection within the clock spring just not in the plug that goes from the radio to the clock spring. And 99 percent of the ones I am seeing for sale are all the same part number. At this rate my optimism hasn't panned out so we'll see haha

 

I made a video of my working steering wheel controls. But my phone will not allow me to change the format so I can upload it here.
Oh well. I followed the directions on here and everything works. When I ordered my controls I did not realize they were for a tacoma so I had to move the pins as described in an earlier post I also had to swap the tacoma circuit board also to keep the backlights the same color. Tallyn91 you had a great write for all steps needed to be taken. Thank you.

 

Did you get yours to work?

 

J45 is the black harness behind the plastic where i circled in red. 139 is behind the stereo. Just count the pins to make sure you have the right one. Thats what I did and everything came out great.

 

Glad to hear it man! So did you have to add the wires to the pins from the steering wheel to the radio connector? Haven't done mine yet cause I've been busy with the holidays but did get my head unit in and flashed. What an improvement

 

How did you add them to the connectors?

 

I "backyard hacked it" to be honest. I removed the entire harness from the old steering wheel controls on the right hand side and used those pins and wires. But I had to stuff them in there really hard. Then I just spliced the other ends and ran wire to complete the connection as they weren't long enough. But everything is electrical taped and not in danger of shorting out on anything.

 

Just got my hands on the tundra steering wheel with controls and finding that only the "mode" button works too! How hard was it to get the wire from the clockspring to the back of the radio? Looks like a really tight cavern in there

 

It not bad once you have the stereo out and the two piece plastic steering column removed there are many locations to run the wires through. And only needing two wires helps. I probably should have found the original harness and run the two wires Long side of it but hindsight is 2020. Lol
Follow the directions from tallyn91 and you'll be fine.

 

I took mine to the dealer to install the new wheel as the computer and wheel alignment also done, over my head to try myself.

 

Yeah if you look at the picture he posted you don't actually have to get behind the clockspring. From what I gather you just turn the wheel either way to reveal two screws. Take those out, remove the lower plastic (that the steering wheel tilt goes through) and there's a plug there that you wire two wires to; pics in this forum will guide you. When installing my maestro I found it easiest to run a snake tool rod from the head unit area down to the driver floor board. Then attach the wires to the rod and pull the snake out to get the back end of the wire up to the radio. Will save you a shit ton of hassle and headache. Then attach to back of headunit connector.

I haven't actually gotten to run the two wires yet since its fucking cold here lol but come spring when I do I'll take some pics and make a separate write up.

As he also said you could try to find the full harness from a yard and do that instead.

 

I hear you it is cold out. I just warmed up my truck before trying it. And it is actually a really short distance to run the wires so no snake needed.

I just got the A/V input harness and will be taking out the stereo again soon so if I think of it I can take pictures of the wires I ran.

 

Yeah it's probably a lot easier to just run speaker wire down. Trying to run some of the bulkier connections for the maestro was gonna be a pain and it saved me a lot of time.

What are you doing with your A/V? Cam? thought about doing something with mine as well but haven't decided what. I'd rather just pull the radio out one more time since I have a giant mess of wires back there now lol

 

Yeah I get that. Lol
I plan to run a chromecast but now I need to get a rca to hdmi converter.

 

Just got this done today because the weather isn't so bad where I'm at. HUGE thanks to everyone that chimed in on how to wire - I took some pics of the process too for those that still are hesitant.

I'm a little OCD about trying to keep things OEM, and I wasn't sure what pins fit in our connectors. Luckily, on some other forum/thread I found that one guy sells pigtails for the connectors. You'll need 4 if you're going this route, and he can be reached at tahirmallick@hotmail.com. The 4 pins you'll need are the same for both J139 & J45, and they are female pins that you'll need.


If you want to follow along with the OEM wiring, you'll need about 3ft of wire for each connection between the clockspring connector and receiver connector. Pushing in the pins is easy once you figure out how the connectors lock - just make sure to lift up the connector lock on each before trying to push in the pins. The locks won't come out all the way, but will lift up maybe about 1-2mm. Pins will only go in one direction due to the tab on the pin sticking up. If you're wondering where the numbers start on each connector, no worries: the connectors will have the bottom corners marked with their respective pin number and you can go from there.



I also freaked out at first when I saw that my stereo connector had all 28 pins filled on the stereo, until I remembered that I had the FRAC harness installed. Kind of interesting to see all 28 pins filled by an aftermarket vendor. I just put the pins in the original connector and everything worked just as it should. Hope this helps someone in the future, and thanks again to all that chimed in here to provide pointers on how to do it.

 

Hi. Just bought a 14 SR so looking to do what you guys did and have a few questions.

1- did you have to do any modifications to the airbag or the airbag capsule in order to fit the additional controls or were you able to use your factory airbag?

2-has anyone gone the pick and pull junkyard route with this and gotten the wiring loom from the spiral cable to the back of the stereo complete from a scrapped tundra?

3- anyone have the factory service and wiring manual? I’ve found links and nothing works. I do a lot of diy and mods (03 Tacoma) and not having the fsm is no bueno. Thanks for the help.

 

1) No modifications necessary to the airbag or airbag capsule. You will have to remove the airbag though in order to remove the wheel's left side blank - should be about two screws and then it will pop off, starting from the bottom of the piece.

2) no. at least in my area, the pick-n-pulls don't have many tundras at all, let alone 2g/3g tundras
3) you don't need the FSM. just read over the guides in this install and you'll be fine. if you're using the tacoma controls then you need to just swap out 2-3 pins within the control. then for the connector underneath the steering wheel, just draw out literally 2 wires to get it working with the radio.

 

Follow the link in my signature for any/every Tundra wiring diagram from 2000-current.

 

Does anyone have a part number or a link where I can get the four pin connectors for the two wires that need to be installed? I have already installed the controls and just need the wires to complete the upgrade. I'm taking my 2017 SR in to get remote start put in this weekend and the guy said he would run the two wires for me at no extra charge but I'm not sure if he is going to have the pin connectors needed on hand. Id rather be on the safe side and bring them with me just in case. Any help would be greatly appreciated.

 

sent you a PM, as I'm not sure if posting private e-mails is allowed
