1. the horns came each with a bracket I used. You can see in the link a photo of the horns with the bracket. It’s simply a metal bar with holes in it at each end. A horn mounts and the center mounts to a structure already on the car behind the grill that already has a hole in it.
2. I don’t know if the kit is a bosch style relay or not. Here’s a link to the one I used. It’s for 5 relays, but I use them on other projects. These have sockets and pigtails. I just splice wire on to extend them.

3. Reach down between the radiator and the headlight on the driver side, you can feel/see the horn and connectors. This is a spade lug fitting. I take the hot wire off the horn and add a spade lug piggyback that allows a second spade lug to split off the horn. I take this second lug and attach a wire from it to the relay switch. This voltage activates the relay with very low amount of current. The relay has a wire from the battery, through a fuse that is on the normally open side of the switch. The other side of the switch goes to the new horns. First to the closest horn, then a jumper over to the second horn. This way, I not only power the new horns with it’s own power source, but the original horns are still in operation, merely providing a very small amount of current to switch the aftermarket relay. You can find many types of spade piggy back connectors on Amazon. However, any sort of wire tap will work just as well. The piggy back doesn’t in any way modify the factory wiring and that’s why I used that style.
4. Yes. See my answer in question 3.
5. The link to the Amazon relays have two pictures. One is of the wiring by color and relay terminal number and the other is a schematic showing the relay coil and it’s contacts; normally open and normally closed. You should be able to figure out from that. However, here’s some instruction by wire color;
BLACK- attach a ring lug and place under any bolt to the body. This is ground. You can use an ohm meter to measure between your bolt and the battery ground to ensure it is indeed ground.
WHITE- attach to the factory horn hot lead. Either use a spade lug piggy back or tap the hot lead wire. Verify it’s the hot lead by removing it and attaching a volt meter between this lead and your newly grounded BLACK wire. When you hit the horn in the car, this should indicate 12VDC on the meter and make the passenger side horn sound. You may need someone to assist. The BLACK wire and the WHITE wire will now make the relay click when the horn is sounded. This click is the contacts inside the relay activating. You can also feel the click with your finger on the relay if it’s too loud to hear.
BLUE-this wire connects to the car’s battery through a fuse. You can buy a fuse pigtail on Amazon. I used this one in the link;

There are many other types, but I have a stock of these as well as relays in my garage already. You will need a fuse as well. The horn
RED- to the horn. I wire to the first horn, then jumper to the second
YELLOW-not used

—-NOTICE—–
There is a horn wire harness kit you can buy that includes the relay, fuse and all the connections I think. You may find this MUCH easier than buying everything ala carte and assembling yourself.

6. It sounds incredibly LOUD! First time I was trying it, I had a wire disconnected. I asked my wife to press the horn when I said as I wiggled wires around. When I found the intermittent connection and the added horns went off, I went deaf for a few minutes! Ha! I then put on my shooter’s ear muffs and continued.
