Is this a 4 prong relay?I am using it for an air horn relay,since the one that comes with those harbor freight horns seem to go out quickly.

This relay has 5 terminals 2 for the coil and for the contacts you have a common, normally open and normally closed,hope this helps

It is a 4 pronged relay, I used it as a bypass which worked so I dont see why it wouldnt work as a relay for your air horn.

I used the relay and did not cut any of the original wires when I installed these. I used the original horn harness to trigger the relay. The original connection on my car was a simple press fit spade connector, so it was easy. If your car has a fancier connector it might be more difficult to avoid cutting some original wires.

No, no need for a relay. There isnt enough amperage. I've had mine for a while with no problem the only thig id do is use different (more durable) wire.

It does. It is basically just a timed relay. I believe the maximum current is around 10 amps. Which is huge for an outlet. You'll be good to go.

I used 14 AWG stranded, because I use it as a constant fan for my truck. I also used a relay with an inline fuse to the battery for power, grounded to a good ground for power and switch ground. I attached the positive of the relay switch to a switch leg and back to a power source that is only on when the key is in the ignition at on position. check your manual or use a multimeter and test fuses that are only on with the key and off when the ignition is off. This protects your battery from drain and your electrical system from a fire. Maybe over kill but I had a vehicular fire under both gasoline and electrical (not proud of it just grateful to be alive). I hope that was of some help.

Marvin, this should do nothing with your Air brakes. You will just tie in the relay with only the Stereo components. You will use 1 ground wire, 1 trigger (from the stereo), and the E-brake wire (also from the stereo).. really simple to use.. I hope this helps.. Thanks.

I think it was 3 prong. I don't know because the units failed rapidly and I discarded them about a month after the purchase.

The wiring is small. Smaller the wire smaller the amp rating. The wire was 14gadge and I used a 15 amp in line fuse with it. I only used it for the wolo horn.

It draws less than 2 amps each. Once installed, I measured both lights at the same time and I remember it was beetween 3 and 4 amps. I didn't even install a relay-

IT is 4 prongs but it is the marine connection. Is that what you have on the 50 amp side?

It's all self contained. It is very loud for a small set of horns as well. You will need a 12 volt relay (about three to five dollars) as it requires more amps than just passing voltage through a button.

The switch and wires are extremely light duty. I cant see it withstanding more than 10 or 15 amps. I used one to replace the horn button on a 50 year old truck. Although the truck is 12 volt, the horn button goes through a relay first.

I am not an expert, so please check with a qualified tech. That being said, I simply drilled two holes where my previous horn was for the air hoses to get through. Then I ran those hoses to the small compressor. They included one with the kit, but I purchased the upgraded one that looks the same but is a little bigger. The compressor wires then get attached to the relay, horn switch and positive and negative wires, one with a fuse. For something without a large tank attached to it, I can't believe how loud it gets. Quite impressive.

the electrically operated (or triggered) air solenoid is mounted in between the horns.you are correct an AIR SOURCE is required for these AIR horns - they are not electric.all the is require is an air source & 12v trigger

I'm not sure what you are looking at, but I would simply parallel the new horn with the old one. Then unplug the old one. You would be using the factory relay to make the horn work.

There is no DC amperage rating on the relay. At 120v it is rated 12 Full load amps and 60 Locked rotor amps. At 277v it is rated 6 Full load amps and 35 Locked rotor amps. I am using mine to control a 24v. 40va transformer and it has been working fine since September.

No, I don't think so, this has a 3 prong plug in, I believe yours is 4 prong
