You need to know that a relay has two circuits, a coil circuit (also called a “low current circuit”, or “inductive circuit”), and a high-amperage circuit. 5-Pin-Relay-Wiring-Diagram-On-Relay-CaseĪccording to DIN 72552 Standard, each pin of a relay is numbered 85, 86, 30, 87, and 87a. Below is the circuit diagram of the four and five-pin car relays. Here we will only discuss the relay’s connection points. DIN standardizes almost every connection point in an automobile with code. The standard code for electrical connection points is known as DIN 72552 standard and is almost accepted throughout the world. The DIN organization also gives a standard DIN code to motor vehicles. This national organization gives standard numbers (Known as DIN Standard) to almost every field of technology, covering almost thirty thousand DIN Numbers. It stands for Deutsches Institut für Normung means the German Institute for Standardization. In the last century, Germany made an organization called DIN Standard. Stick with me, here I am giving you a little background about automobile relay connection points. Here in this section, I am explaining the 12 volt electrical diagram of the four and five-pin car relays. All you need to know is the basics of a car relay wiring schematic. The automotive relay wiring diagram is not complicated, it’s very easy.

It is a device that uses an electromagnet to open or close a circuit. Each circuit has its pin numbers and wiring diagram. It is made up of two circuits, a coil, and high amperage circuit. An automobile relay is an electrical switch, which turns ON and OFF by giving an electrical trigger. Relays are important in vehicle applications because they can help prevent voltage drops, which can damage sensitive electronic components. FAQs What is A Relay And How Does it Work.
