WebSo you should connect pin 86 to +12, pin 87 to the horn wire, and to make the horn beep, you ground pin 85. If you have only a positive signal for "horn" then you can add a small 12V relay to operate the horn relay or … WebThus, a 12V DC coil that has 120 ohms of resistance pulls 0.1 amp of current. Some relay coils accept DC voltage, while others accept AC voltage. DC (direct current) voltage has a constant, unchanging value. At any given instant of time, a 12V DC power source measures exactly 12 volts (give or take a few tenths of a volt, normally). (See Fig. 1A)
