    30 and 87 - the circuit which we want to switch on with the relay


    85 and 86 - power supply of the relay coil (switching on).

    Pin 87a is a "switched" pin, ie after applying voltage to 85 and 86, circuit 30-87 switches on, and disconnects 30-87a. This contact is used when you want to disconnect the circuit by energizing a relay.

    Not really, this is a terminal that is powered directly from the battery, sometimes it matters. The rest as above.

    And would someone give a diagram with such a relay, i.e. current from the battery through the relay to the switch and to the working halogens?

    Thanks in advance.

    From the position lamps.

    It can be from terminal 30 or + from the battery. But in this case, when it comes to halogen lights + to control the relay, it is best to connect to the parking lights power supply. This is how it is attached to most cars.

    It cannot be straight from the plus, because the halogen lights are to shine together with the positional ones.

Topic summary

The discussion revolves around the pin configuration of a relay, specifically identifying the functions of pins 30, 87, 87a, 85, and 86. Pin 30 is connected to the power source, while pin 87 is used to switch the circuit on. Pins 85 and 86 are for powering the relay coil. Pin 87a serves as a switched pin that disconnects the circuit when the relay is energized. Users also inquire about wiring diagrams for connecting the relay to halogen lights, with suggestions to connect the control to the parking lights power supply for proper operation.
