How to Wire a Relay (4 Pin and 5 Pin Demonstration)

Рет қаралды 15,877

Күн бұрын

Today we are going to show how to wire up both a 4 pin and 5 pin relay. This shows how to wire a relay for light bars, foglight, auxiliary lights, and any other vehicle accessories. We will wire the relay up with a switch, a 12V source and a few lights. We will demonstrate the 4 pin relay with a single LED light, and then the 5 pin relay with dual LEDs to show the operation and wiring.
A relay is an electromechanical switch that consists of a set of input relays and a single or multiple outputs. It is the easiest way to isolate a load from the switching circuit that you are using.

Nicely done my friend. I find anything electrical to be very puzzling, almost black magic shite. But you explained this well. Thank you!

Yes, great video. I had an old(er) truck once and used a relay to operate the off road lights.

@SmackeysGarage Жыл бұрын

Thanks Shane. I'm thinking of doing the same thing with my truck but have them by controllable reverse lights with a switch. Something I can turn on if needed, but doesn't always need to be used.

@bardstables8909 Жыл бұрын

@Smackey's Garage yes, hooking up a trailer in the dark makes lights extremely valuable. Also placed some in my bed since my truck is older. That little cargo light above the cab just doesn't cut it.

That's what I'm hoping. Connecting or even loading the snowmobile trailer is tough without extra light from the truck.

Could u do a diagram on how to wire a chopper with this method. Just headlights brake lights ignition system oad have it start and shut off with a toggle switch and relay its harley sportster

Can you reply say I want to run both at the same time which relay would I need I’ve subscribed and good videos

@SmackeysGarage 2 ай бұрын

What amperage or wattage are the lights you are trying to run? Thanks!

Great video, thank you! Just one question: I have a relay with two 87 outputs (so both 87s are hot at the same time). One 87 supplies the Pertronix system with 12V. Would the pertronix still have full 12V, if I put an electric choke to the other 87? Or is it a bad idea?

@SmackeysGarage Жыл бұрын

It depends on the loads and if the relay can handle them. The choke really doesn't take much of a load itself since it is just heating up a bimetallic strip. I'm not sure how much load the Pertronix system takes. If it is anything setup like an MSD system, they recommend going straight to the battery for the 12V supply. If the total current is less than the relay, you should be ok.

Can this be used for an aftermarket backup camera to provide two power sources? One power source being the reverse bulb wire trigger for backing up and then a toggled constant power source from the battery.

@SmackeysGarage 3 ай бұрын

I don't see why not. Are you looking at adding the two power sources to 87/87a and then the camera off of 30?

@steve-o9720 3 ай бұрын

@SmackeysGarage yes. If I can make it work in reverse? Or would a 3 way switch be a better option? Running a trigger power to one pole and constant to the other?

@SmackeysGarage 3 ай бұрын

@steve-o9720 if you use the relay it’d all be automated, which I personally like. You should be able to use relays in that manner. I believe that’s the way they do it in a lot of marine applications and control applications.

Hey Smackie, I’ve a question, I’m gonna wire almost the identical pair of halogens, 21,000Lms each on my pontoon. Can I splice both halogens into one relay? My relays are the same as your 5 pin as well. So if I can use only one relay, in order to have both lights on, I merely disregard the 87a pin, correct? Thanks for your help. Love your vids!

@SmackeysGarage 3 ай бұрын

That’s how I’d do it. Id make sure there are fuses protecting yourself if there was ever any short. Are they halogens or LEDs? Should also check the total amperage they’d be drawing.

Oh and thank you!
