This can be confusing at first. Using a cutter, cut the loop in the middle to make two separate ends for the fuse holder.Strip each end and crimp the supplied 8-gauge ring terminal to one side. ON the opposite end, crimp the 8-gauge to 10-gauge connector, as shown below.<img src="https://uploads.gorgias.io/mJQz875pXo2adpn4/undefined-01260571-ae23-4181-9fb4-46be34829157" style="width: 467px;" class="fr-fic fr-dib">The end with the ring terminal will attach to the battery positive terminal on your vehicle. The opposite end of the fuse holder will be connected to the red power wire out to our relay.<hr>Main Power WireLocate the roll of 10-gauge power wire that was included with your kit. This wire will be used to connect from the fuse holder to the 40-amp relay.&#xA0;<img src="https://uploads.gorgias.io/mJQz875pXo2adpn4/10AWG-WIRE_1800x1800-c1902528-97a2-439c-b47c-3de66f5dfbf0.webp" style="width: 631px;" class="fr-fic fr-dib"><span id="isPasted" style="color: rgb(65, 65, 65); font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; float: none; display: inline !important;">Start by stripping one end of this red power wire and connect it to the smaller end of the crimp connector on the end of the fuse holder. Crimp the wire into the connector to complete this connection. Make sure it is tight and does not come loose. <img src="https://uploads.gorgias.io/mJQz875pXo2adpn4/undefined-86effaf0-8365-430c-92dd-0e38516d2b7e" style="width: 622px;" class="fr-fic fr-dib"><span style="color: rgb(65, 65, 65); font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; float: none; display: inline !important;">Route the red wire through the vehicle back to the air compressor/tank. Find a good location to mount the relay. Make sure the relay is close enough to connect to the red wire coming off the compressor/tank. Do not connect this wire yet.<span style="color: rgb(65, 65, 65); font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; float: none; display: inline !important;">Strip the opposite end of the red wire and crimp the tan-coloured terminal connector onto the wire as shown below.<span style="color: rgb(65, 65, 65); font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; float: none; display: inline !important;"><img src="https://uploads.gorgias.io/mJQz875pXo2adpn4/undefined-8a1d3e71-9e11-4c37-9285-11f2d1b3ea9f" style="width: 615px;" class="fr-fic fr-dib">Connect this terminal connector pin 87 on the relay. This is the pin that runs sideways, instead of vertical like the other 3. See the following image:<img src="https://uploads.gorgias.io/mJQz875pXo2adpn4/undefined-08762041-bb1f-49b5-8ab7-6a20bf10b9df" style="width: 461px;" class="fr-fic fr-dib">Your main power is hooked up and ready for use. Let&apos;s finish up the other pins on the relay.<hr>Relay GroundThe ground (-) for the relay is extremely important. If the relay doesn&apos;t have a proper ground, it won&apos;t work and the compressor will never kick on and fill the tank.&#xA0;To start, locate the roll of grey or blue 18-gauge wire that was supplied with your kit.<img src="https://uploads.gorgias.io/mJQz875pXo2adpn4/Grey-Wire_2048x-4c7abf5f-69a3-409a-9fe0-2bc767546506.webp" style="width: 626px;" class="fr-fic fr-dib">Strip one end of this wire and crimp one of the small red female terminal connectors onto the wire.<img src="https://uploads.gorgias.io/mJQz875pXo2adpn4/undefined-46461764-94a9-4511-957c-b90ee2848b75" style="width: 538px;" class="fr-fic fr-dib">Connect this lead to pin 85 on the relay, as shown below.<img src="https://uploads.gorgias.io/mJQz875pXo2adpn4/undefined-7f089028-d60c-42fe-8aca-7fc0120bad84" style="width: 561px;" class="fr-fic fr-dib">Route the grey wire to the frame of the vehicle (or back up to the negative battery terminal). Use the supplied 18-gauge ring terminal connector to secure the wire to the frame as a ground (or negative battery terminal). Do not use the tool box or bed as a ground, these will not work. The frame MUST be used!&#xA0;<img src="https://uploads.gorgias.io/mJQz875pXo2adpn4/undefined-83e6c39f-ef2c-4736-8051-59a3054bda26" style="width: 513px;" class="fr-fic fr-dib"><hr>Relay Trigger (this is what tells the relay to turn on)This connection will use the 18-gauge grey or blue wire similar to the last step. We will crimp a terminal connector onto one end of the wire as we did previously, and connect this terminal to pin 86.&#xA0;Your relay will look like this:<img src="https://uploads.gorgias.io/mJQz875pXo2adpn4/undefined-f61e6239-ae60-403a-9245-ee4ec44e508e" style="width: 453px;" class="fr-fic fr-dib">With that connected, we need to find a good key-power source to tap this into. A good key-power source would be something like the cigarette lighter, radio, or an upfitter switch (if applicable).&#xA0;You can use the included t-tap connector to splice off a wire that is key-power on. The radio or cigarette lighter are usually the easiest to do. If you can&apos;t find a good key-power source, you can use the included toggle switch instead to turn the relay on/off. Only problem with that is if the toggle switch is left on after you park, the compressor could run while the vehicle is off. The following example shows how a t-tap connector could be used to tap into the OEM horn. You can do the same but with an accessory +12v wire instead of the OEM horn.<img src="https://uploads.gorgias.io/mJQz875pXo2adpn4/undefined-380b0f24-163d-4e51-9d4a-1ea220ae76a3" style="width: 588px;" class="fr-fic fr-dib"><hr>To finish the relay, connect the red wire from the compressor over to the last remaining pin on the relay. This will complete the relay wiring.&#xA0;<hr>Running the CompressorGo ahead and insert one of the 30A fuses into the fuse holder (30A - Green Fuse).Ground the black wire from the air source over to the frame of the vehicle.&#xA0;Turn the key over and listen for the compressor. It should start to run and fill the air tank with air.&#xA0;

OverviewAir horns are becoming an increasingly popular way to signify a goal in sporting events across the nation. HornBlasters horns are commonly used on vehicles but can also be used in arena&apos;s for sporting events or just as a warning device. This guide goes over the different ways this can be done with 110v power.Air SourceAt the heart of any horn system is the air source. You can&apos;t honk air horns without air! Deciding on an air source for your application can be tough. The chart below lists a few different models we would recommend for use with our horns.&#xA0;<table style="width: 88%; margin-right: calc(12%);"><tbody><tr><td style="width: 21.5569%; background-color: rgb(209, 213, 216);"><img src="https://uploads.gorgias.io/mJQz875pXo2adpn4/undefined-3c595430-4e36-43ed-b176-52510b660844" style="width: 80px;" class="fr-fic fr-dib"></td><td style="width: 18.3446%; background-color: rgb(239, 239, 239); vertical-align: middle;">Rigid Pancake Air Compressor</td><td style="width: 17.113%; vertical-align: middle; background-color: rgb(239, 239, 239);">Husky &quot;Hotdog&quot; Compressor</td><td style="width: 15.0289%; vertical-align: middle; background-color: rgb(239, 239, 239);">Dewalt Heavy Duty Compressor</td><td style="width: 16.1195%; vertical-align: middle; background-color: rgb(239, 239, 239);">Husky &quot;Silent&quot; Air Compressor</td><td style="width: 9.025%; vertical-align: middle; background-color: rgb(239, 239, 239);">Husky Oil-Free XL Portable Compressor</td></tr><tr><td style="width: 21.5569%;">Reservoir Size</td><td style="width: 18.3446%; background-color: rgb(255, 255, 255);">6 Gallons</td><td style="width: 17.113%;">8 Gallons</td><td style="width: 15.0289%;">15 Gallons</td><td style="width: 16.1195%;">20 Gallons</td><td style="width: 9.025%;">27 Gallons</td></tr><tr><td style="width: 21.5569%;">Continuous Honk Time (with Shocker XL Horns)&#xA0;</td><td style="width: 18.3446%; background-color: rgb(255, 255, 255);">12-15 Seconds</td><td style="width: 17.113%;">16-20 Seconds</td><td style="width: 15.0289%;">30-35 Seconds</td><td style="width: 16.1195%;">40-45 Seconds</td><td style="width: 9.025%;">~54-60 Seconds&#xA0;</td></tr><tr><td style="width: 21.5569%;">Refill Time&#xA0;</td><td style="width: 18.3446%; background-color: rgb(255, 255, 255);">100-120 Seconds</td><td style="width: 17.113%;">90-110 Seconds</td><td style="width: 15.0289%;">3.5 Minutes</td><td style="width: 16.1195%;">5 Minutes</td><td style="width: 9.025%;">9-10 Minutes&#xA0;</td></tr><tr><td style="width: 21.5569%;">Operating Pressure</td><td style="width: 18.3446%; background-color: rgb(255, 255, 255);">150 PSI</td><td style="width: 17.113%;">150 PSI</td><td style="width: 15.0289%;">200 PSI</td><td style="width: 16.1195%;">165 PSI</td><td style="width: 9.025%;">200 PSI</td></tr><tr><td style="width: 21.5569%;">Website Link</td><td style="width: 18.3446%; background-color: rgb(239, 239, 239);"><a href="https://www.homedepot.com/p/RIDGID-6-Gal-Portable-Electric-Pancake-Air-Compressor-OF60150HB/303379052" rel="noopener noreferrer" target="_blank">Click Here</a> </td><td style="width: 17.113%;"><a href="https://www.homedepot.com/p/Husky-8G-150-PSI-Hotdog-Air-Compressor-0300816/302862402" rel="noopener noreferrer" target="_blank">Click Here</a></td><td style="width: 15.0289%;"><a href="https://www.homedepot.com/p/DEWALT-15-Gal-Portable-Electric-Air-Compressor-D55168/302918678">Click Here</a></td><td style="width: 16.1195%;"><a href="https://www.homedepot.com/p/Husky-20-Gal-Vertical-Electric-Powered-Silent-Air-Compressor-3332013/311273546" rel="noopener noreferrer" target="_blank">Click Here</a> </td><td style="width: 9.025%;"><a href="https://www.homedepot.com/p/Husky-27-Gal-200-PSI-Oil-Free-Portable-Vertical-Electric-Air-Compressor-C271H/312074154" rel="noopener noreferrer" target="_blank">Click Here</a></td></tr></tbody></table> Choosing a HornPicking out the best train horn for your application is just as important as the air source. In most cases, your best bet is to go with our Shocker XL horns or even the Nathan Airchime series horns. The Shocker XL is more budget friendly whereas the K5LA is the loudest horn we offer. The K5LA is more commonly used for larger venues due to it&apos;s output volume. Our K5LA is even used in the Mercedes Benz stadium in Atlanta, GA.&#xA0;<a href="https://hornblasters.com/pages/atlanta-falcons-stadium-train-horn-install?_pos=2&amp;_psq=mercedes-benz&amp;_ss=e&amp;_v=1.0" target="_blank" rel="noopener noreferrer"></a><a href="https://hornblasters.com/pages/atlanta-falcons-stadium-train-horn-install?_pos=2&amp;_psq=mercedes-benz&amp;_ss=e&amp;_v=1.0" rel="noopener noreferrer" target="_blank">More info on that here.</a>Adapting our horns to the compressors listed above is extremely easy and can be done with the aid of one fitting. A 1/4&quot; NPT x 1/2&quot; PTC fitting can be used to adapt from the tank&apos;s existing outlet port to the 1/2&quot; line we use with our kits. <a href="https://hornblasters.com/products/1-4-male-npt-to-1-2-ptc?_pos=1&amp;_psq=ft-4m8&amp;_ss=e&amp;_v=1.0&amp;variant=3026844450856" rel="noopener noreferrer" target="_blank">Check it out here.</a>&#xA0;You can remove the 1/4&quot; quick disconnect fitting from the compressor and replace it with our fitting instead. The quick disconnect on the compressor looks like this:<img src="https://uploads.gorgias.io/mJQz875pXo2adpn4/undefined-dced72ad-41aa-4a78-b3c0-0dec029d5eb2" style="width: 333px;" class="fr-fic fr-dib fr-fil">Unthread this fitting and thread ours in it&apos;s place. Make sure to use some Teflon tape on the thread of the fitting so it doesn&apos;t leak constantly.Wiring Options&#xA0;The horns can be setup with a 110v valve instead of the 12v valve we normally offer. This allows you to honk the horn with power from your venue without having to keep a car battery handy.

To make this work, the positive wire to the OEM horn must be cut. If you are unsure as to which is the positive wire, do not cut anything. We recommend starting at the connector and going back ~6-8&quot; so you have plenty of wire to work with. Cut the wire in half, and strip each end. If you&apos;re unable to tell which wire is the positive wire, you can use a voltage meter to test both wires.<hr style="box-sizing: border-box; height: 1px; border-width: 1px 0px 0px; border-right-style: initial; border-bottom-style: initial; border-left-style: initial; border-right-color: initial; border-bottom-color: initial; border-left-color: initial; border-image: initial; border-top-style: solid; border-top-color: var(--colorBorder);">The RelayThe Single-Pole Double Throw relay you are working with has five posts on the bottom.</div></div><div style="box-sizing: border-box; margin-left: auto; margin-right: auto; position: relative; text-align: center; max-width: 500px; color: rgb(0, 0, 0); font-family: Montserrat, sans-serif; font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.35px; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; opacity: 1;"><img data-fr-image-pasted="true" data-src="https://i.shgcdn.com/a9c2cf30-6029-46ea-bcd7-a60dbf6f5e21/-/format/auto/-/preview/3000x3000/-/quality/lighter/" width height alt src="https://i.shgcdn.com/a9c2cf30-6029-46ea-bcd7-a60dbf6f5e21/-/format/auto/-/preview/3000x3000/-/quality/lighter/" style="box-sizing: border-box; border: 0px; max-width: 100%; min-height: inherit; max-height: inherit; opacity: 1; transition: opacity 300ms ease 0s; height: auto;" class="fr-fic fr-dib"></div><div style="box-sizing: border-box; margin-left: auto; margin-right: auto; padding-left: 15px; padding-right: 15px; max-width: 1200px; color: rgb(0, 0, 0); font-family: Montserrat, sans-serif; font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.35px; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;"><div style="box-sizing: border-box; margin-left: auto; margin-right: auto; max-width: 1400px; overflow-wrap: break-word;">This relay is very similar to the 4-pin relays we use with some of our kits. The added post &apos;87A&apos; is used for a second accessory. These relays are designed to switch between two circuits, when on or off. You will set this up so that one circuit is for the regular stock horn and the other is for the train horns. Both can be honked with the steering wheel, but only one at a time will honk.<ul style="box-sizing: border-box; margin: 0px 0px 25px 30px; padding: 0px; text-rendering: optimizelegibility;"><li style="box-sizing: border-box; margin-bottom: 0.5em;">87: Connect the wire from OEM horn (the short wire lead we cut earlier FROM the horn itself.

These two pins are a part of the relay trigger. +12v power comes into pin 86, flows through a coil in the relay, and flows out to the ground point that pin 85 is connected to. This creates an electromagnet in the relay which moves a metal arm which connects pin 87 and 30 together. When power is cut, the relay clicks &apos;OFF&apos; and the metal arm disconnects pin 87 and 30 from each other.&#xA0;<hr>Car Battery MethodGrab your 40A relay and wires. Pop the hood of your vehicle and locate the battery. Disconnect the negative terminal of the battery to prevent any sort of electrical interference with the vehicle.&#xA0;Take one lead of your 18-gauge wire and connect it to the negative terminal on the battery. Take the opposite end to pin 85 on the relay. You may need to use an electrical connector to hold the wire place.&#xA0;Take the other lead of wire and connect one end to the battery positive terminal. Connect the opposite end of the wire to pin 86 on the relay. When you touch the wire to the terminal, the relay should click immediately. The click means the relay is in the &apos;ON&apos; position, or the arm inside has connected pin 87/30 together.If the relay does not click, double-check and make sure your connections are good. If the relay does not click still, it is probably no good.<hr>9-Volt Battery MethodGrab your 40A relay and 9-volt battery. Locate pins 85 and 86&#xA0;on the relay as shown above. Take your 9-volt battery and line it up so that the positive terminal touches pin 86 and the negative terminal touches pin 85. Touch the battery terminals to each pin simultaneously. The relay should click once both terminals are connected.&#xA0;<hr>
