You don’t have to be a wiring guru to understand the principle of an electrical relay.
Quite simply, relays are essentially switches that can be remote-controlled.
They work by using the principles of electro-magnetism.
When energized by a simple 12-volt source, the magnet will either turn the electrical switch on or off.

Wiring a relays is pretty basic, but can be confusing to folks without a ton of electrical experience.
The folks over at Dorman made this quick, one-minute video that walks you through a typical automotive relay’s wiring procedure.
It’s a quick watch, and very useful in understanding what you’ll be working with when installing a relay.
Thank you, this was needed.
My God, I am so glad they did this public service. My family is so appreciate of this.
I have found out over the years that nothing works better then a wiring diagram. Even a simple one that would have fit in this 40 second quickey.
What about 5 pin relays?
A 5 pin relay works the same as a 4 pin relay. With a 5 pin you have a closed circuit and an open circuit. When the coil gets powered it pulls the spring loaded contact arm to either open or close a circuit. You can make a set of wig-wag lights with a 5 pin relay and an automotive flasher. The flasher just is to operate the coil.
I am old school, I straight wire everything and use fuses wrapped in aluminum foil. Never had a problem.
You are kidding, right?
Wow! What a piece of chit.

How do I post pictures of my projects on your website. I don’t do facebook, twitter, or any social media types. I can mail in pics or cd disc with pics on it, or email attachments. Thanks, ted
Good for you. Only an idiot would give facebook and all the other computer companies personal info to be sold
