Do Relays Need To Be Grounded. In any circuit with a din relay, without looking at a wiring diagram, you know that: Be sure to choose a relay that can handle your voltage and current requirements to ensure the relay coil doesn't burn out and your circuit doesn't get. It closes the switch contact that connects the fat cable from the positive battery terminal to the windings of the starter motor itself. So lets just focus on what an automotive relays is. Because the starter is grounded to the battery through. Eric.the solenoid is grounded usually by mounting it to some part of the chassis which is in turn grounded to the battery. A relay does the same. So you should connect pin 86 to +12, pin 87 to the horn wire, and to make the horn beep, you ground pin 85. You will usually see 3, 4, and 5 prong. If you have only a positive signal for horn then you can add a small 12v relay to. Terminal 86 supplies power to the relay’s internal electromagnet. Terminal 30 supplies power to one of the internal switch contacts. Terminal 85 grounds the electromagnet. The second pin, or ground is the housing which must be mounted direct to chassis or otherwise grounded. If your relay is in a plastic housing it will have 2.

If you have only a positive signal for horn then you can add a small 12v relay to. It takes the incoming voltage and once grounded will send that voltage to other places. So you should connect pin 86 to +12, pin 87 to the horn wire, and to make the horn beep, you ground pin 85.
