In this episode we installed a horn taking advantage of the buttons on the steering wheel and feeding it from the same power supply of the 12v sound amplifier board.
That is, I connect the positive of the horn to the two cables of the steering wheel that I have joined with a faston and the cable that remains from the steering wheel that is the common to the positive of the plate, I only have the negative of the horn I will connect it to the negative of the license plate.
Greetings and thank you.
