Determine that the relay is an iso micro type.

Mini relay 4 pin micro relay wiring diagram.

4x4 and off road forum inside relay 4 pin wiring diagram image size 640 x 480 px and to view image details please click the image. A open your fuse box and try see if there is any unused 4 pin mini or 4 pin micro relay sockets. Look for a relay diagram or a relay schematic that is printed on the side of the relay to determine. 87 and 87a are the two contacts to which 30 will connect.

If the coil is not activated 30 will always be connected 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. When a relay contact is open the relay is not energized. 85 and 86 are the coil pins while 30 87 and 87a are the contact pins.

These layouts are shown on the two 5 pin relays below pin 87a not present on 4 pin relays. Note that each pin is numbered. Relay diagrams pirate4x4. Here we look at relay switch pin diagram and the different kinds of relay switches.

Looking at the diagram we see the pinout of a typical 12v 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. Numbers of a relay. The iso defines this type of relay as 1 inch 2 5 cm by 1 inch 2 5 cm by 0 5 inches 25 4 mm by 25 4 mm by 12 7 mm.

Relays switches are used to open and close circuits electromechanically or electronically. You will notice that on the type b layout pins 86 and 30 are swapped over compared with the type a layout. I have attached the electrical wiring diagram from the turn indicator i believe what you will discover is that the turn signal and hazard the 8 pin flasher relay toyota is using here is kinda alien to me. Here is a picture gallery about relay 4 pin wiring diagram complete with the description of the image please find the image you need.

An iso micro relay has the control circuit connected to pin 86 and pin 85 and the load circuit connected to pin 30 and pin 87 or 87a. 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.
