Review on 🚗 Enhance Your Vehicle's Sound with iJDMTOY 12V Horn Wiring Harness Relay Kit (Compatible with Car Truck Grille Mount Blast Tone Horns) by Niko Knight

If the wiring was connected properly this would be a nice little harness. All the ground wires were bundled together which is good, no splicing but they were plugged into an 87a socket for a five pin relay that would close the case instantly. Use the supplied four-pin relay. Socket 87a is not used. Ground goes to 85. The big red wire goes from the battery post to 30. The smaller red wires for powering the horns go to 87. If you want to connect it to an existing system, the black and red round wires go to 86. If you want to hook it up to a car without a horn, run a wire from the battery connector to the horn button and then from the other connector to the horn button at 86. That will work. When I got mine all the cables were defective. I didn't expect it to take my neighbor and I two hours to figure this out BECAUSE IT WAS CONNECTED INCORRECTLY. end of the connector and along the back (non-exposed side) of the spade connector. There is a small metal tab that is used to snap the connector into the connector and hold it in place. This allows you to rearrange the connectors in the correct direction if necessary. Just be careful not to damage the connectors or plug, and don't hit your arm with the screwdriver.
