I NEED TO HAVE SOMEONE HELP ME ON A WIRING DIAGRAM FOR THE HORN CIRCUIT. I BOUGHT THE RAM W/AIR HORNS WHICH DIED, HAVE THE TWO ORIGINAL HORNS ON THE BUMPER (DRIVERS SIDE) BUT NO WIRING TO THEM. NEED TO KNOW HOW TO CONNECT THE HORNS SO THEY CAN WORK FOR STATE INSPECTION.

I looked at info for a Silverado 1500. Use a test light to check for voltage at horn fuse in under hood fuse box. According to this diagram, the horn relay has to be energized. Have a helper hit the horn switch when you check voltage at horn fuse. If hot, have to check wiring circuit to horn. In the diagram, dark green wire is voltage and black wire is ground. You could actually use jumper wires from battery for voltage and ground to horn, for testing.
Check to see if there is 12 volts at the horn positive connection when someone pushes the horn button on the steering wheel. If there is voltage, and no sound, you need a new horn. If there is no voltage when the horn button is pressed, you need to troubleshoot the rest of the electrical circuit. First look in your fuse box for a blown horn fuse. Then try replacing the horn relay.
Could be a short in the steering wheel or column. Or a faulty horn relay. You may need a wiring diagram to trace the circuits from the relay. Usually the black wire is the ground and the green is voltage from the relay.
Honda makes the Integra but it uses the Acura name in the US. According to the wiring diagram the brake lights and horn are on the same circuit. So I would check the bulbs and sockets for a short. The brake light switch also involves the cruise control system.
First of all, there is no wire that runs from the horn to the steering column (if the horn circuits had been properly diagnosed you would know this). I would recommend diagnosing and repairing the horn circuit the correct way rather than butchering your wiring harnesses and adding more problems to the electrical problems that you are already experiencing.
If you would like help with diagnosing and repairing your truck's horn circuit, I would be happy to help you do that.
Finding the room to mount it is the hardest part depending on the type you buy. You will need to test fit it into a few different positions until you find the right spot. Best not to point them into areas they will get wet or too much air pushing into them. They can be mounted in pretty much any direction.
The easier way is if you eliminate your original horn, and hook the 12 Volt power supply from the original horn, to the Air pump that will come with your horns, or that is attached to the horn. If you have to extend the connecting wire, make sure you have a secure connection at both ends
To have both horns, you'll need to install a special switch from the interior to a Heavy Duty 12 Volt relay in the engine compartment that you install, the relay will need to have amperage high enough to match the horns requirements, then connect it through a "Fused" circuit from the battery.
They usually put those instructions on the package.
That's it. You press the horn switch, it energizes the pump & instantly provides an air horn sound.
Unplug the wire to the horn and make sure you have the horn grounded really good. Take a hot wire and run it from the battery to the horn. touch the hot wire to the end of the horn and see if it works. If it does not work then you need to replace the horn. If the horn works then take a test light and hook it up to the horn wire and have someone push the horn down. you should have a hot wire. If you don't them check the horn fuse. Let me know if this works.
