LED Enabled Steering Wheel (How to get power from wiring harness)

[siddhartha.y91]

Hello Namja, thanks for your thoughts.
I don't think that the fuse will work. The steering wheel rotates, and so it would be a very bad practice to route the wires through a rotating clutch beneath the airbag, in order to connect to the power source. That said, I spoke to a technician at my local dealer, and he shared drawings with me, and I'm now working to get the wheel wired up properly.

If you look at the 1st diagram, you can see two wires identified as Illum +, and Illum -. These two wires power the lights within the steering wheel. I've tested them, and they provide 12 volts, and they should work.
The problem is how do I attach the wires from the LED bar, to these pins, on the Clutch Connector. I'm working through this problem now, and hope to have it resolved and the wheel working within a week.

From where did he get this diagram.?
Owners manual.?

I see a 10A fuse on the left side of the steering column, behind the wheel, but can't tell what circuit it's protecting (no service manual info from what I've seen so far)

How did you remove it.?
Any videos.?

Good morning. Hey I was looking through the threads and saw that you had ordered your steering wheel from socal garage works. I also ordered one a few weeks ago. I was curious if you ever ended up getting the wiring done for the leds to work? I got mine with the leds and the heated option. So, was just curious on how I was to wire these up. Im guessing the illumination positive and negative leads worked? What color were those wires? Did you get the heated wheel or no? If so howd you hook those up? If you wouldnt mind showing a pic of the wheel. Id like to see it. I cant wait for mine to show up. Thanks for any help you can provide. Take care. You can find me on here or on instagram at reaper33333.

Hey I was looking to purchase one of these carbon wheels with LED and heat option and was wondering how the heat function is working. Also if you could let me know what wire you used for the connections.

Heating function works fine, I would say ot doesn’t get as hot as the OEM steering wheel but it’s much thicker and a lot of carbon fiber so the trade off is worth it imo. It still gets pretty warm when needed.

My mistake was having my mechanic hook up the steering wheel to my night headlights so my steering wheel LEDs only come on at night or when I manually turn on my headlights. Kind of annoying when I want it during the day.

There was an option that I regret not doing now, which was hooking it up to your heating steering wheel button. I’m trying to figure out how to do that myself right now as I would like to have an on/off button and it not be my night time lights.

Has anyone put a multimeter on the steering wheel illumination pins (3 - B/W & 4 - Y) and changed the dash illumination?

Do these pins keep a constant 12v or do they vary with dash brightness?

No switched 12v source in here unfortunately, I have probed around. Illumination will work with the lights only.

I was hoping to find linearly variable voltage that dims the steering wheel button lights alongside the dash lights.

Hmmm.

I’ve done quite a bit of automotive electronics over the years but I am sufficiently inexperienced with airbags that I’m overly cautious opening up steering wheels.

I would like to check voltages of the steering wheel button illumination wires (3 - B/W & 4 - Y) while operating the dimming switch. This requires the battery to be connected and the airbag out of the way at least a few inches. The airbag wires look long enough to enable this.

First step to REMOVING the airbag is to disconnect the battery. This makes obvious sense if I’m going to manipulate the electronics to the airbag itself, but if I’m only moving the CONNECTED airbag a few inches out of the way…is disconnecting the battery required?

Thanks.

Negative! airbag does not need to be unplugged to probe around. It has enough slack to hang just use a microfiber to lay it so you won't sctech your steering wheel. But just to let you know, the illumination wires only work with the headlight switch. So if you plan to connect it to those wires the steering wheel will only work with the parking lights/headlights.

For everyone else! I have a teaser for you soon!

Right. Airbag does not need to be unplugged. But does the battery need to be disconnected?

I mean to be on the safe side yes! but honselly not needed if your being careful. Because you need the battery connected for testing obviously.
