Technical airbag spring clock

[bollie69]

Hello,

I own a barchetta and bought myself a fiat 500 abarth steering wheel.
Others told me it wouldn't fit but I made it fit

The axle is the same and has the same amount of splines on it. But on the 500 you have 3 big ones to center the steering wheel and you can't put in on wrong.

I solved this by cutting away 3 splines on the axle and removing about 3mm of the steering wheel so It could go down all the way over the axle.
The steering wheel fits

It was never my intention to make the airbag work. this won't work because of the multistage airbag, the barchetta has only 1 stage.

But what I would want to work is the multifuntion steering contols to control my pioneer radio and control my aftermarket cruise control.

What I want to know of you guys is if all 500 clocksprings for the airbag are suited for multifuntion control. Or do some have an extra wire?

In this stage I don't know if I will need the clockspring by itself or the complete stalk assembly (wiper and light switches) to make it fit on the barchetta.

Would someone have a clockspring that is busted so I could try to make it fit.

Anyone got some tips where to find the right parts I need, probably from someone who is braking a 500

edit: ow btw I got some other 500 parts on the B.
I got the blackjack wheels with the black abarth caps

Modifying the splines on the steering wheel?
= / Scary stuff! You sure it's safe?

I took away 3 splines on the axle where the big ones could fit in of the steering wheel.
Its not a bit unsafer than before.
It's not as drastic as you think.

But that's not the case. I have driven some km with it and it does not give a problem.
Just need to make the multifuntion buttons work.

No one who can tell me if there is a difference in the clock spring for cars with or without steering controls.?

I would, if I knew... I'm guessing that all mechanically minded people are either busy, or don't know what you are talking about Good luck!

Steering controls on the 500 and most modern Fiat's are CANBUS operated, without serious modification and stripping them down I doubt you'll get them to function. It certainly won't be plug and play with an adapter!

The 500 is canbus right.
But the steering wheel controls have just buttons and some wire.
I can't see why I couldn't just use this on my radio.

When you buy a stalk lead you connect the steering wheel controls with your aftermarket radio. Thats the same as I'm upto I recon.

It seems like per side there are 5 wires going to both button pads wich have 4 buttons.
Seems to me all wires are getting power from one wire, and when you press the button the correspondenting wire of that button gets the power thrue.

I think i can manage that
Found the clockspring on ebay in the uk... finaly
Now to get it working... I have 2 options.

Getting the clock spring to fit my stalk controls or getting to fit the complete stalk control + clock spring to my cars wiring loom.
I've got about 3 for spare so that isn't a problem. but I will need those connectors to go inside of the stalk unit of the 500

I found here on the forum there are 500 with cruise control buttons on the steerinng wheel. that's what I'm after next.
Will try to make my cc fit on that

Thats not what I've seen from someone else whos fitted one of these to another car. Apparently there is a small controller for the buttons which sends different voltages depending upon the button which is pressed (hense being canbus operated on the recieving end)

I'd be very surprised if there are 10 wires going to a clock spring just for audio controls, just if you've checked then no reason you can't give it a go.

For reference though patch / stalk leads for modern Fiats are canbus integrated also - is it on my Bravo hence costing about £40 and having a control module to interpret the signals from the buttons and convert them to something the head unit will recognise.
