    my onlu concern, is that the reciever of the horn , would get noise from the RF Remote that i will have inside the wheel, but since the remote is at 2.4ghz, i could get a reciever that works at Mhz...

    If you could find a compatible car with steering wheel controls and use the internal parts that would be the best way to do this. Otherwise do you need the remote to be IN the steering wheel? You could always mount it in a panel bolted to the steering wheel column and not need to mess with the internals of your wheel.

    Baring either of those you could also use a multi channel remote if you can fit everything inside your steering wheel. (Does your car have an air bag in that year? I hope you are not disabling the air bag? )

    A multi channel remote would have a bunch of inputs that you could then send to the receiver to decode. You can use something such as a Aduino Nano as a transmitter and another as a receiver and do whatever you want with them. These should be very small and have the ability to have as many outputs/inputs as you want and you could have a wireless or IR transmitter to do your work. They are easy to program and very flexible. In this type of setup you really only need to close contacts so it should be easy.

    Something like this depending on your room:

    Irrelevant. If it's 2.4G it is digital and won't interfere. (Neither should analog for that matter.)

    redhead- my car is from the 1992, so i wouldn't worry about airbags (it has none). of course i agree, that finding a part thatr feets my car, and has cable pass option, in the slip, and then use the OEM buttons, is by far the most STABLE, option.
    but not neccecery the best... apart of the fact that i did searched for parts like that, but here in greece, i can never find what i search for, it would limit me to the design of the buttons, (now i have used BMW x5 buttons), AND it would still requiore external software/hardware to translate the car buttons, to computer actions.... in the build i have atm, i have a 2.4Ghz RF remote, that connects directly to the pc, and has direct actions on it. the buttons, are parallel-wired with the buttons of the wheel..

    after all it was RF that did the trick. i went and bought a 1channel communication kit, that controls a relay (although i could have build one ) with pin-codes and staff liek that for no RF Noise. So now, all the signals from the steering wheel go out, wirlessly, and the OEM cables, carry just power. i will post a complete thread when i am done!
