Automotive relays are not all the same. There are many different types of automotive relays, each with their own specific purpose. The most common type of automotive relay is the starter relay, which is used to activate the starter motor when the ignition key is turned. Other common types of automotive relays include headlight relays, horn relays, and fuel pump relays.
A relay is an electrically operated switch that can be used to control a circuit using a low-power signal. Relays are often used to control high-power circuits such as motors or lights. They can also be used to switch between two different power sources. Most relays have four terminals: two for the coil, one for the common connection, and one for the normally open connection. If the relay has a fifth terminal, it is for the normally closed connection. Relays can be either normally open or normally closed. A normally open relay has a closed circuit
There are a few things to consider when choosing a relay. The first is the voltage. You will need to know the voltage of the device you are trying to control. The second is the current. The relay should be able to handle the current of the device. The third is the coil resistance. This is important because it will determine how much power is needed to operate the relay. The fourth is the switch rating. This is the maximum current that the relay can switch.
A 5 pin automotive relay contains 5 terminals which are used to control the relay. The first terminal is used to control the coil which is used to activate the relay. The second terminal is used to control the input voltage. The third terminal is used to control the output voltage. The fourth terminal is used to control the ground. The fifth terminal is used to control the open or close position of the relay.

This relay harness is lovely and of excellent quality. The fact that it is for the smaller "micro" 280-sized relay and not a standard-sized relay is the issue I experienced with it. If the larger relay wasn't necessary, I would have saved and used this. Even though the item is made in the USA and the quality is clear, I am still giving it a five-star rating. The relay size needs to be more clearly stated in the yjust. The right one from Hella does not include Prime shipping, which is a drawback: (

I bought these to isolate my truck's headlights.Small and with directions for use clearly marked on the bottom. If you know how to wire a relay, no instructions are necessary.People who don't.The relay is powered by the fuse panel at position 30. (you must use circuit protection inline to this terminal)The ground connection is 85.86 is the trigger number to activate the relay (from your switch in the vehicle)The link to the light you're shining is at 87.

These relays served me in two ways.1. to disconnect switching and my plow's lighting from my truck's harness2. to shield my truck's headlights from the naive Chrysler engineers who believed it was a good idea to run everything through the ignition switch.made very good. Nearly too inexpensive for what you receive. also purchased the sealed connectors with 12" leads.https://www.amazon.com/gp/product/B000VU9D0C/ref=cm cr ryp prd ttl sol 7The only thing I didn't like was that I already had a set of relays, and they were set up slightly differently. The relays are clearly indicated, making them simple to follow, but here's how it happened.The component is indicated for the 30amp input on the bottom pin. The top pin is the switched to pole from the 30 amp input, the left pin is the ground, the right pin is the trigger switch, the center pin is the common, and the top pin is the feed through pin. I acquired a second pair as well as leads for my headlamps because I loved them so much and wanted to replace the truck headlamps I had installed a few years earlier even though they were in perfect condition. Knowing that everything is fresh and well-sealed will be soothing.

Yes, a kit comes with everything, however...I made the decision to go find each part separately while I waited for this to arrive so I could have my truck back (HEI swap on a ford 400). I discovered that you can get these components separately for just half the cost. Additionally, the wire (12 ga. and 10 ga.) I purchased came in 30-foot lengths, so I still have a good 20 feet of wire left over. In addition, I still have a ton of electrical connectors from the kit I bought (Walmart has everything). Good product, but too expensive. Spend less money and go out and find the parts yourself. It's also more enjoyable.

For my fans, good relays. The wires are well sized for current draw, and the instructions were simple to follow. Personally, I believe fuse holders for battery locations might have been included (had to purchase those separately), but I would still purchase this kit again.

Worked fantastically, exactly as promised. However, based on customer feedback, they should consider including a small wiring diagram for the extremely precise wiring connections that must be made. Unlike standard relays, this one is more like an older German flasher relay that requires a specific voltage, either positive or ground, on a specific terminal in order to function at all. It is a positive trigger only relay because the timer inside requires a positive and a negative on particular terminals in order to latch. Therefore, to change the trigger polarity if you have a negative trigger switch, you will need to utilize another relay.They found other people who made the same comment on Google, but they only mentioned the placement of the positive battery feed, not that the negative battery feed also had to be on a specific terminal, otherwise would be 5 stars. They could demonstrate this with a straightforward block diagram and a few simple words.

I wired up a high amperage, PWM (pulse width modulated) engine cooling fan using two of them, and I'm extremely happy with how well they worked.According to the Hella website, this relay can handle 22 amps at its highest operating temperature.Use many relays wired in parallel to meet the maximum operational amperage plus 15% of your equipment. I utilised two relays for a total of 44 amps because my fan draws 35 amps. 35 amps plus 15% equals 40.25 ampsThe wiring is different, but this relay can fit in a standard socket and has the same pin numbers as a typical relay.Battery 3087 = Load (High Amperage)85 is a zero.Switched Ground, 86
If you are adding more than one additional accessory to your car that will draw power from the electrical system, you will need a relay. The number of extra accessories and their wattage will determine how many amps you need before you need a relay. For example, if you are adding two 100-watt light bulbs, you will need a relay that can handle at least 10 amps. If you are adding four 100-watt light bulbs, you will need a relay that can handle at least 20 amps.
An automotive relay can handle up to 30 amps.
Automotive relays are devices that use a small amount of current to control a larger amount of current. They are commonly used in automotive applications to control things like lights, fans, and other accessories. Most automotive relays have a coil that is rated for a specific amount of current. When the coil is energized, it creates a magnetic field that closes the contacts inside the relay, allowing current to flow through. The amount of current that flows through the contacts is limited by the coil's rating.
If you're changing a relay, it's generally best to disconnect the battery. This will help to ensure that you don't accidentally short something out and cause a fire or other damage.
Automotive relays are devices that are used to control a circuit by opening and closing the circuit using an electromagnet. The electromagnet is activated by a small electric current, which in turn activates the relay. Relays are used in a variety of automotive applications, such as headlight control, fuel pump control, and starter solenoid control.
An 87a relay is a changeover relay with an 87a pinout. This means that the relay has eight pins, with the 87a pin in the middle. The other pins are numbered 1-7, starting from the left. The 87a pin is used to control the voltage and current flow through the relay.
