Aftermarket steering wheel horn issue...

I just received the Dali Racing steering wheel hub. Wanted to make the horn work knowing that the horn wire needs to connect to a ground to work.

Had to sand down some of the black paint on the Dali hub to make have continuity through both peices.

After assembling, I find that the steering spline is not grounded. Not sure if it was something I did but I know that the OEM wheel horn botton is grounded to the spline.

any ideas? what could I have done to lose the ground on the steering spline?

Thanks in advance.

Call Dali... MJ is usually very helpful with his products...

PLEASE... all you haters... don't start another rediculous thread off of this comment.
 
I might have figured it out. The cable OEM cable reel sends the horn signal to the Cruise Control unit before linking to the Horn wire. When you look inside the connector, you see that the horn wire is an open pin which needs to be connected to the Cruise switch. A simple wire short should do the trick. Just have to buy a couple of small connectors.

I'll test tomorrow to confirm.

BTW, Dali racing was great. The item arrived 2nd day on a Saturday. Items were carefully wrapped and in perfect condition. No complaints from me.
 
Hi Lithiumus,

I was hoping to get some feedback from you about an aftermarket horn button issue that I have which sounds similar to your dilemna....

I have attached a wire onto the black connector for the horn button and tried to ground it to the spline to get it to operate the horn.. I could have sworn that previously when I had a Sparco quick release, that the horn would sound when I touched a wire connected from the black female horn connector to the spline...

Well, I recently ordered an SOS quick release hub which has a connector that plugs right into the OEM black horn connector. But NOW the horn doesn't work.

I tried to test it the same way I previously did, but now it doesn't work again. I am not sure what to do at this point. I am sure that the relays are fine and so are the horns... Any suggestions? Maybe a bad cable reel, or probs with my SRS connections?

I would appreciate any help that you can provide.

Thanks alot in advance!

Hi Michael,

It sounds like the same issue I had. The black OEM horn connector does not connect to anything. It requires the cruise switch to be connected to extend the ground signal to that connector.

I just bought some small connectors and wired up a short out wire and connected the ground signal to the horn connector inside the cable reel yellow connector. That seems to work. Also make sure that your new hub has continuity throughout. Good luck.

Garrick,

Thanks alot for the help. I really appreciate it. It appears upon further research that Chris at SOS forgot to send me the wire that completes the bridge between the cruise signal and the horn signal in the yellow 4 pin connector. :mad:

Do you by chance remember which of the 3 pins besides the horn pin in the yellow connector is the proper one to bridge for the horn signal?

Thanks in advance!
-Michael.
 
Follow up on this issue:

I finally was able to get the horn button working. You need to jump the third pin in the yellow cruise control plug with the separated 4th horn pin. This can be done by bridging the 2 pins with a small wire with connectors. This will complete the circuit as Lithiumus stated above.

Chris at SOS, you mentioned that there is also a bridge wire for the SRS connector to cancel out the SRS light on the SRS yellow plug as well. But you still need to bridge the pins in the Cruise plug as well. Thanks for the help that you attempted to provide.

Also, thanks to Malibu Rapper for borrowing the equipment. ;)

-Michael.
 
Hello MIchael,

I've recently bought Rapid steering wheel hub and NSX-R horn kit and having trouble making the horn to work. From your latest post, I tried to wire it as best as I could based on your note. Please see the photo, but did I mis-understood the connection method?

For anyone that have bought this combo, please help me with this issue.

Thanks in advance!

The one thing that might be missing here is the grounding signal. You can see a metal contact point bottom side of the ring in the photo where the horn expects to be grounded.

I now can't remember which after market part supplied this i.e. wheel, hub or button... but I have a metal ring which mounts between my hub and steering wheel where the center extends up through the wheel center. That is where that metal piece connects to the ring which connects to the hub and grounds through to the spline.

If you don't have that metal piece, you'll have to gound the steering wheel by ensuring continuity to ground via the mounting bolts and wherever the horn ground touches the steering wheel.
