Paddles on steering wheel

[Jota5sport]

Hello,

Is it possible to wire the paddles as the diagram-02 or diagram attached files?

Im limited to 2 wires on the steering wheel, negative and one signal


Thanks

If it is needed I will add it soon
there is no problem with the first one
is the second configuration necessary?

[Jota5sport]

The second one is necessary in the w210 as it only has 2 wires for the steering

If it's possible it will be perfect for us

Thanks man

The resistors are originally assembled, Can other resistors be used? The mass of the blades will have to go to the TCU Sensor Ground
There is a 10k Ohm pull up in the TCU, For this reason there will be small voltage changes you would have to install 20K ohm pull up or replace the resistors with other

Yes no problem, I can use any value of resistors.

I have available Pin 31 A1 and Pin 19 SGround, for the horn output I can use an AUX I think

Hello Luki,

What resistors should I buy for the second picture?

Thanks

this is a proven configuration and the program will do it for it

Great info.
How do I do the programing in tunerpro for this setup, volt ref table etc, and having the third value trigger the horn output channel?

The Lamik team has written instructions on how to program this function:
