Automotive 5 pin micro relay wiring diagram. In this video i show you how to wire a 12 volt automotive bosch style relay. The interior mounted switch only draws minimal power though the interior fuse block to activate the relay. Look for a relay diagram or a relay schematic that is printed on the side of the relay to determine. 84 1040 5 pin relay pigtail assembly with mounting bracket 12v.

A 5 pin relay has a single control circuit but two separate current paths for the switch. One when the relay is de energized off no current through the control coil and the other the energized on current is flowing through the control coil. The difference between a 4 and 5 pin relay is that a 4 pin relay is used to control a single circuit whereas a 5 pin relay switches power between two circuits. If you want a normally closed relay you will want to wire to 87a.

4 pin relay 4 pin relays use 2 pins 85 86 to control the coil and 2 pins 30 87 which switch power on a single circuit. Protection diode and spike suppression resistor for automotive relays. 84 1076 relay 5 pin. These layouts are shown on the two 5 pin relays below pin 87a not present on 4 pin relays.

This video covers both 4 and 5 pin 12vdc relays. Output for a relay. The automotive iso mini relays we have been looking at above are typically available in two types of pin layout designated type a and type b layouts. Buy relays pigtails and kits here.

Although most relays are labeled at the bottom you can always find the 30 pin set perpendicular to pins 87 and 87a for easy identification to the power source. Wiring with a relay allows the power to run straight from the battery through the relay mounted nearby directly to the lights. Mini micro relays. See below for an example of a relay wiring diagram.

In a diode protected relay mini relays must be pin 85 power pin 86 ground micro relays must be pin 2 power pin 1 ground. You will notice that on the type b layout pins 86 and 30 are swapped over compared with the type a layout.
