4 Pin Relay Wiring Diagram For Lights This guide will help you identify the 4 pins, understand their function, and take you step by step through wiring a 4 pin relay. it’s an easy task that you can manage on your own. wiring a four pin relay is a simple three step process: connect pin 85 to the ground. connect pins 86 and pin 87 as the switching pins. Wiring diagram for a 4 pin relay. a 4 pin relay is a device used in electrical circuits to control the flow of current. it is commonly used in automobiles for various purposes, such as controlling the headlights, horn, or cooling fan. understanding the wiring diagram for a 4 pin relay is essential for proper installation and troubleshooting.
Understanding 4 Pin Relay Wiring Diagrams Moo Wiring How to properly wire a 4 pin relay for lights fan and accessories. wiring and connecting a 4 pin bosch style relay is super easy with my easy to follow wirin. To wire a 4 pin relay, you need to connect the common pin to the power source, the normally open pin to the device you want to control, and the normally closed pin to the ground or earth. the control pin is connected to a switch or a control module that activates the relay. by using a 4 pin relay, you can safely control high current devices. 1. identify the wires of headlights: the first step in order to wire the relay for the driving light is to identify the wires coming out of the driving lights. normally, there are two wires connected to these lights out of which, one is the power wire, normally having a red color, and another one will be ground wire black in color. 2. Step 3: identify the relay pins. before wiring the relay, you need to identify the different pins. a 4 pin relay typically has four pins labeled as follows: 85, 86, 87, and 30. pin 85 and 86 are used to control the relay, while pins 87 and 30 are used for the connection of the power source and the load.

Step 1: gather all the necessary materials and tools for the job, including a 4 pin relay, wire cutters strippers, electrical tape, and the appropriate gauge wire for your specific application. step 2: familiarize yourself with the pinout diagram of the 4 pin relay.
